Effects of welding technology on the occurrence of fracture in welded joints
(Elsevier Science Bv, Amsterdam, 2018)
Welded joints represent locations where failure is most likely to occur in welded structures. Welded joint failure depends on their vulnerability to crack initiation and growth. These factors are significantly influenced ...
Analysis of strain distribution in overmatching V groove weld using digital image correlation
(Elsevier Science Bv, Amsterdam, 2018)
Welded joints are treated as critical sites when constructing and calculating welded structures due to inhomogeneity and anisotropy of materials at the welded joint site. Because of the change in the geometry of the elements, ...
Microhardness and Macrostructures of Friction Stir Welded T-joints
(Elsevier Science Bv, Amsterdam, 2018)
The results of research regarding the friction stir welding process of T-joints are presented in this paper. Experimental welding of two and three aluminium plates were performed in order to obtain T-joints. Microhardness ...
Numerical Simulation of Fatigue Crack Growth in Hip Implants
(Elsevier Science Bv, Amsterdam, 2016)
In this paper numerical analysis of hip replacement implant behaviour from a fracture mechanics perspective is presented. It is necessary to understand the fatigue crack initiation and propagation characteristics in order ...
Material characterization of the main steam pipeline made of 12%Cr tempered martensite ferritic steel after prolonged service
(International Conference on Fracture, 2017)
In the past decades, tempered martensitic ferritic steels with 9-12% chromium and containing carbide stabilizing elements have been widely used for components which operate within the creep range in power and industrial ...
The development and application of the new methodology for conveyor idlers fits testing
(Elsevier Science Bv, Amsterdam, 2018)
The proper interference fit between the joined parts is a prerequisite for an effective pressure joint. The main purpose of the pressure joint is to transfer tangential, radial and axial loads between the joined parts. In ...
Development of numerical-experimental model of connecting lugs and application on the lugs calculation of container terminals
(Elsevier Science Bv, Amsterdam, 2018)
The present paper describes numerical and experimental methodology and development of the model for stress and deformation state analysis of the connecting lug of container terminals. Numerical analysis was conducted by ...
With frequency simulation to design the monitoring of frame structures
(Institute of Physics Publishing, 2018)
Based on experience from the testing of the mining stacker in the copper mine in Bor, a practical procedure of frequency simulation of the enforced vibration of the structure was demonstrated. Modelling of the excitation ...
Influence of semi-circular cracks on threaded connection fatigue by means of Kitagawa-Takahashi diagram and El Haddad equation
(Trans Tech Publications Ltd, 2016)
Evaluation of semi-circular surface crack influence on threaded connection fatigue behavior, made of 42CrMo4 heat treatable steel, was carried out. Crack diameters were defined as 0.02, 0.05, 0.1, and 0.15 mm. Influence ...
Hydrogen embrittlement of low carbon structural steel
(Elsevier Science Bv, Amsterdam, 2014)
Hydrogen embrittlement (HE) of steels is extremely interesting topic in many industrial applications, while a predictive physical model still does not exist. A number of studies carried out in the world are unambiguous ...
