Weibull probability distribution for reactor steel 20MnMoNi55 cleavage fracture in transition temperature
(Elsevier, Amsterdam, 2020)
This paper presents the results and methods used for determining of fracture toughness of reactor steel, denoted as 20MnMoNi55, typically used for structures working at low temperatures, in transition temperature area. In ...
Dual Phase Austempered Ductile Iron - The Material Revolution and Its Engineering Applications
(Springer International Publishing Ag, Cham, 2020)
During the last few years, there has been an increased interest in improving the strength of ductile iron by means of heat-treating to obtain dual phase microstructures that enhance the properties found in the Austempered ...
Thermalhydraulics of once-through steam boiler tubes revisited
(Department of Thermal Technology, Gliwice, Poland, Silesian University of Technology 2020, 2020)
The analysis of pressure changes in water and steam flow along the entire once-through steam boiler
tube system was carried out. An efficient advanced method is developed and presented for the
prediction of once-through ...
Influence of second-phase particles on fracture behavior of PLA and advanced PLA-X material
(Elsevier Science Bv, Amsterdam, 2021)
Most widespread materials in Additive Manufacturing are PLA (PolyLactic Acid) and ABS (Acrylonitrile Butadiene Styrene), which are dissimilar materials in terms of printing abilities and mechanical properties. PLA material ...
Composite material selection for aircraft structures based on experimental and numerical evaluation of mechanical properties
(Elsevier Science Bv, Amsterdam, 2021)
In this paper determination of mechanical properties of composite material using experimental and numerical approach is presented. The mechanical properties of a laminate obtained in the experiment are used for verification ...
Numerical simulation of fatigue crack growth in AA6156 T6 panels
(Elsevier B.V., 2021)
Fatigue crack growth in a panel with 4 stringers and 3-clips, made of AA6156 T6, was modelled numerically using xFEM. The central crack of the length a=17 mm was propagated in the total of 91 steps (in each step crack ...
Crack propagation in 3PB specimen made from welded joint
(Elsevier, Amsterdam, 2020)
Crack propagation in 3PB specimen has been investigated experimentally by using Digital Image Correlation (DIC) technique. For this purpose, specimens were taken from butt welded plates, made of P460NL1 micro-alloyed steel. ...
Economic Implications of Innovative Visual Guidance System for Crane Cabins
(Springer, 2020)
This paper proposes innovation through implementation of a real-time computer-aided visual guidance system (VGS) which prevents crane accidents, caused by crane operator’s obstructed view, which can be the cause of collisions ...
True Stress-strain Curves for HSLA Steel Weldment - Iteration Procedure Based on DIC and FEM
(Elsevier, Amsterdam, 2020)
True stress-strain curves of HSLA steel welded joint regions were estimated by using numerical simulation of strains measured by DIC and special iteration procedure to match the results. Strains were measured at certain ...
Rules of Risk Management - Case Study of Open Pit Mine
(Elsevier, Amsterdam, 2020)
The issue of human factor risk and rules and regulations in open pit mine is a main focus of this paper in order to develop predictive models of behavior of workers in relation to compliance with the procedures and rules. ...
