AB  - The contact fatigue is a localized phenomenon that occurs in highlystressed local zone of the material under the loaded contact region and as such ishighly nonlinear problem. This phenomenon exists in almost all real mechanicalsystems with contact strains coupled with other sources of nonlinear behaviour.The improvements of existing procedures and methods for standard calculationof contact fatigue have a potential to give significant contribution to increaseaccuracy of calculation of life assessment, reliability and efficiency of complexmechanical systems.

AB  - In spite of numerous and expensive research in the field of fatigue and fracture and regular control of end products, cracks occur every day in all fields of human activity. This paper describes failure analysis of chain brackets, used in conveyor systems for cement production. Chain type bucket elevators utilize chain brackets for joining segments of chain as well as for attaching brackets for bulk material transport. The contact zone between chain link and bracket is one of the most stressed in this elevator system. During regular maintenance, cracks are found on used and new brackets in the case hardened zone. Case hardening of the chain bracket is performed due to requirements for increased wear resistance of the chain link contact. The occurrence of cracks in new brackets raised the question regarding the origin of cracks and it is the main subject of this paper. This paper also suggests a solution for avoidance of cracks on chain brackets.

AB  - During the last few decades, the requirements for modern machine elements in terms of size reduction, increasing the energy efficiency, and a higher load capacity of standard and non-standard gears have been very prevalent issues. Within these demands, the main goals are the optimization of the gears’ tooth profiles, as well as the investigation of new tooth profile designs. The presented design idea is based on the optimal solutions inspired by nature. Special attention is paid to the new design of the tooth root zones of spur gears in order to decrease the stress concentration values and increase the tooth root fatigue resistance. The finite element method is used for stress and strain state calculations, and the particular gear pair is modeled and optimized for these purposes. For tooth root strength analysis, the estimations are based on the theory of critical distances and the stress gradients obtained through finite element analysis. The obtained stress gradients have shown important improvements in the stress distribution in the transition zone optimized by biomimetics. An analysis of the material variation influence is also performed. Based on the investigations of a particular gear pair, a significant stress reduction of about 7% for steel gears and about 10.3% for cast iron gears is obtained for tooth roots optimized by bio-inspired design.

AB  - Composite materials have been extensively employed in the aviation industry in recent years. The application of new materials enables significant weight savings with improved mechanical characteristics. This is also very important in the field of development of unmanned aerial vehicles (UAV). In the design phases, it is necessary to perceive all the aspects that are important for the structure and consider different load cases. The relationship between weight and strength proved to be important. This means that detailed strength analyses of each structural part are indispensable. In particular, primary load-bearing structures must sustain all types of loads without fail. Failure of the structure can affect the motion of the UAV during the mission or lead to a crash and significant losses. This paper presents the research performed on the failure analysis of a composite beam of a novel UAV. During the testing phase, under an unpredictable load condition followed by a crash landing, failure of the structure occurred on a beam element. The study was performed to determine the cause of the failure of certain layers of the composite laminate, because the previous calculation showed that it met the criteria for which it was dimensioned. Based on the telemetry data and the impact load that was registered, a complementary numerical and experimental analyses were performed to determine what happened and why. Composite test specimens were extracted from the beam and subjected to standard tensile tests, in order to determine the actual mechanical characteristics of the layered material. The paper presents in detail the comparison of the results as well as the methodology used in this research.

AB  - The repair of structural elements for the prestressing of reinforced concrete is necessarywhen existing prestressing wires are damaged or after a certain period of time. The objective of thispaper is to describe the methodology for the life assessment of corroded prestressing wires, sampledfrom prestressed concrete elements after a few decades of use. The aim of the presented research wasto determine the real properties of corroded wire in terms of the evaluation of remaining load capacityusing the Theory of Critical Distances (TCD). The methodology also includes spatial 3D characterizationof corroded surfaces, determination of mechanical properties, and Finite Element Analysis (FEA)of a model of wire with corrosion pits. The final goal of the presented methodology is to enable moreefficient evaluation of repair range and options for the elements of mechanical prestressing systemswithin various structures. The results and conclusions indicate that the developed methodology,based on the interdisciplinary approach and implementation of state-of-the-art methods, has a highapplicability potential for both static and fatigue fracture prediction in the case of prestressed wires.The proposed method has a huge potential for simple and fast prediction of the life assessment ofengineering structures, particularly for damaged elements with arbitrary geometry features

AB  - Every industrial product should be adapted and harmonized with existing or potential
needs in various areas of human activity. Basic sciences are followed by technical sciences, which
lead to product development, including engineering design and related activities. After completing
the engineering design, the product is manufactured using appropriate production technologies. Art,
particularly through industrial design, is more or less included in product development, depending
on the type of product. Last, but not least, the state and dynamics of product development are
influenced by the social and economic situation, as well as politics, which create an environment for
all these activities [1]. Otherwise, realized products significantly impact each of these areas of
society and civilization development. A product life-cycle includes the following main stages [1]:
1) Problem/Need/Market and Company Goals/Potential; 2) Product planning; 3) Design/ Development; 4) Parts production/Assembly/Testing; 5) Marketing/Sale; 6) Use/Maintenance and 7) Energy
recovery/Recycling/Disposal. The main steps of product design and development are:
1) Task setting; 2) Concept design/Synthesis; 3) Selection of shapes, dimensions and materials;
4) Analysis/Simulation/ Optimisation; 5) Corrections/Modifications and 6) Detailed drawings.In the
Architecture, Engineering, and Construction (AEC) industry, there is a concept known as Building
Information Modelling (BIM), which has undergone significant development over the past fifteen
years. It represents a modern approach to the design, documentation, delivery, and lifecycle
management of buildings by utilizing project databases in conjunction with object-based parametric
modelling [2]. The primary aim of this work is to propose a comprehensive methodology for
Machine Information Modelling (MIM) to the scientific community in the field of machine design.
It also seeks to initiate the development of a complex methodology tailored to all aspects of
machine design while incorporating valuable elements from BIM. Some certain aspects similar to
BIM principles are already present in machine design and manufacturing, though they have not
been systematized and standardized or unified, as they have in the AEC sector. Our current main
focus is on a multidimensional (nD) modelling approach to MIM. It is necessary to create a very
complex information system that would contain all the mentioned dimensions (or new ones that will
inevitably emerge with industrial development) and provide instructions for their incorporation into
the machine design. This is impossible without the application of modern information and
communication technologies (ICT), the utilization of powerful digital resources, and the integration
of artificial intelligence. Additionally, it is essential to include the process of standardization and the
publication of appropriate standards for the realization of n-dimensional design, similar to those for
BIM, as well as using the unique aspects of machine design, which lead to original MIM. The
number of dimensions is theoretically infinite. The greater the amount of information we
incorporate into a model, the more dimensions we can generate!

of artificial intelligence. Additionally, it is essential to include the process of standardization and the
publication of appropriate standards for the realization of n-dimensional design, similar to those for
BIM, as well as using the unique aspects of machine design, which lead to original MIM. The
number of dimensions is theoretically infinite. The greater the amount of information we
incorporate into a model, the more dimensions we can generate!",

AB  - The high level of worthiness of unmanned aerial vehicles (UAV), particularly in everyday life, is something that will be common thing in close future. The design solutions for UAV us subject of constant innovation, focused on the improving structure performances and weight reducing. The use of new materials. like various composites, is necessary during this process to fulfill such demanding structural design requirements. Despite the fact that such kind of composite made UAV structures are subjected to the detailed calculation procedures and experimental verifications in the design phase, the fracture and failure can occur during testing in real operation conditions. The redesign procedure is required in order to overcome the noted issues.This paper describes failure analysis, as well as structural redesign procedure for a beam element of an unconventional UAV. The fracture analysis is based on the numerical calculations of the deformation and stress state of the element, as well as experimental investigation of material characteristics. The developed redesign solution contains modifications in material of the element, as well as the changes in the structure design of the failure zone. The Finite Element Analysis is performed and discussed for both of the element structures: original design and redesign based on the fracture analysis. The conclusions obtained by the comparison of these Finite Element Analyses show the significant structure improvements in the stress concentration zone, achieved by the proposed redesign.

AB  - New demands placed on industry make it necessary to improve design, real-time monitoring and failure prediction methods for rolling bearings. This paper presents an approach for assessing how contact surface damage affects the vibration response of rolling bearings and how vibration-based monitoring shows the damage level of rolling element bearings. A new parameter named the damage factor is introduced to quantify the vibration response of rolling bearings. The analytical-numerical method for calculation of this parameter is developed based on nonlinear dynamics postulates. The developed method for damage factor calculation is tested on a particular type of radial deep groove ball bearing, and an experimental verification is performed, showing a maximum deviation of 7% in the results. The conclusions drawn from the obtained results and the potential contributions of the introduced parameters for rolling bearing design are discussed. The chosen polynomial function keeps deviations in relation to the calculated damage factor within 3% for failed areas of different sizes.

Six partners from six different countries involved in the project received the drawing of the structure, the material properties, the loading and boundary conditions. Each partner, based on their background and experience in numerical analyses, developed a finite element model with different levels of details and accuracy and performed a blind prediction of the structural behaviour of the wing component. The numerical results are presented and compared with the experimental test data conducted at Cardiff University.

AB  - Hertz contact and the resulting stress-strain state arising from the contact between two elastic solids have practical application in hardness testing, wear and impact damage of engineering ceramics, the design of dental prostheses, gear teeth, ball and roller bearings and many other engineering applications. Although the common concepts for studying these problems implies that the analysis is perform taking into account that elastic solids are imperfection free, the real problems, as well as various failure analysis, underline significance in taking into account those imperfections, [1]. Imperfections in metallic materials can be non-metallic inclusions, carbides, pores and other microstructural defects, [1, 2]. This paper describes model of two cylinders in contact made by metallic material with carbides. The Finite Element Analysis (FEA) is performed in order to discuss the influence of position, orientation and dimension of carbides on Hertz stresses for two cylinders in contact. Fig.1a shows the FEA model developed for calculation the Hertz stress state for two cylinders, and Fig.2 shows the position and dimension of carbides for two of the series of modelled cases.

AB  - This paper contains elements of a comprehensive research devoted to the dynamic behavior of radial ball bearings in real working conditions. The general motivation for this topic comes from the requirements for high performance operation of bearings within complex mechanical systems, defined in many industrial branches during the last decades. The discussion of the fundamental postulates of the approach used for analyzing the vibration response of rolling ball bearings in order to select the optimal working conditions is given. The certain simplifications and reductions used for analyzing the radial ball bearings are explained. The developed procedure can be used for research of influence of different damages and variable operation conditions on the rolling bearings dynamics. The detail analyses of the dynamic behavior of rolling bearings are performed for particular types of radial ball bearings in two case studies: For the damaged outer raceway surface in accordance with real fatigue damage shapes and dimensions and, for variable working temperature. Obtained results are shown by comparative diagrams of vibration and phase plane portraits. Presented results could be a base for more widely research of nonlinear dynamics of radial ball bearings with different damages and for the application of phase plane analysis in order to choose the optimal operation conditions.

AB  - The main performance of involute gears operation leads to the appearance of nonlinear dynamic behavior and impact. In this chapter the influence of mild wear of the tooth flanks of gears without machine finishing and surface hardening on the vibro-impact behavior is considered. For this purpose, a new theoretical model for vibro-impact dynamics of spur gears with mild wear on tooth flanks is developed and described. The developed theoretical model is based on the main postulates of a model of the central centric collision of two fictive rolling disks with radii equal to the radii of kinematic diameters of the pinion and the wheel, as well as on a combined analytical/numerical approach used finite element analysis for the calculation of contact deformations, contact pressure, and wear on tooth flanks surfaces. A particular gear pair for earth moving machine is used for presenting the developed model. The conclusions about the influence of mild wear on the vibroimpact oscillations during running-in period are described.

The developed theoretical model is based on the main postulates of a model of the central centric collision of two fictive rolling disks with radii equal to the radii of kinematic diameters of the pinion and the wheel, as well as on a combined analytical/numerical approach used finite element analysis for the calculation of contact deformations, contact pressure, and wear on tooth flanks surfaces. A particular gear pair for earth moving machine is used for presenting the developed model. The conclusions about the influence of mild wear on the vibroimpact oscillations during running-in period are described.",

AB  - This paper presents the development of a methodology for calculating radial ball bearing vibrations. First, analytical and numerical models were developed and then, the obtained results were experimentally verified. In the experiment, a test rig for a dynamic testing of bearings subjected to an external load was used. Special attention was paid to the analysis of the total bearing deformations and stiffness, being the main parameters that define the dynamic behaviour of a bearing. In order to determine total deformations of a ball bearing as an assembly, a finite element model of the bearing was developed. The results obtained from the new methodology for a particular ball bearing type have been verified by experimental results. The obtained correlations of the experimental and the numerical results are about 2.5%. Based on the calculations and the experimental testing of the chosen ball bearing type, under conditions of a variable radial load, the analysis of the influence of the radial load on the dynamic behaviour of a ball bearing was performed. The analysis of the obtained results showed that the vibration amplitude increases with a similar multiple factor as loads increase.

AB  - Major function of railway vehicles absorbers is to absorb energy through controlled deformation during frontal rail vehicle collisions. The results presented and discussed in this paper is a part of the research of one particular type of absorber consist of a thin-walled seamless tube and conical mandrel. The influence of the groove, which occurred during cold worked tube manufacturing, on the behavior and energy absorption of this type of shock absorber is analyzed. The coupled nonlinear Finite Element Analysis is used for calculation of stress-strain state and plastic deformation work/volume of tube absorbers with defects. The results of the research presented in this paper show that the grooves on outer surface of expansion tubes in some cases can be beneficial due to strain hardening process in root of stress concentrator i.e. defect. The beneficial effect of grooves is proven by simulation in which is obvious that the energy absorbed level could be higher on expansion tube with grooves.

During last decades, the new requirements in machine elements design are placed in front of the experts. The optimization of machine elements is focused on the size reduction, energy efficiency increasing, as well as on the higher reliability. When it is starting to seems that the engineers are without inspiration, the disciplines that returning us to the nature as an inspiration began to occupy the focus. Using biomimetics principles as inspiration, fine optimization of present geometries of machine elements can be done, which will lead to longer and safer life of machines. The good example of solutions offered by nature, with emphasize on design of geometry can be found in the references of few authors dedicated to research in this area. Examples of well-known precise calculations and high "commercial" innovations are found everywhere around us.

AB  - Many new requirements in the field of experimental mechanics, like testing of metallic materials, emphasize traceability and accuracy of test results as the end goal. These requirements have energy efficiency context too, due to the increase of mass productions of many finished and semi-finished products based on steel metallurgy. Combined, both of the above-noted perspectives impose the need for improvements of some of the existing test methods. This paper describes one such improvement, the developing of the new insert tool for testing of shear strength of the welded fabric, for civil engineering. The developed tool allows repeated testing of welded joints sampled from the welded fabric of different dimensions without tool changes and is generally related with the procedure for the determination of shear strength properties of different sizes of wires used for welded fabric. The construction of the tool insert allows aiming high operation safety and higher accuracy of results, which is described in detail. The paper also presents experimental results and the Finite Element Analysis performed in order to verify the impact of insert tool application on the testing results. The obtained results and conclusion about the possible contributions of the developed insert tool for extensively testing of welded fabric for civil engineering are discussed.

AB  - The concept of using ideas from nature as inspiration for innovation and technological development is in focus last decades, while the similar approach can be found in the ancient civilizations. In any kind of such progress it is important to remember the founders and pioneers and to understand their character and the circumstances that push them to go beyond existing knowledge.
