The new experimental testing methodology for conveyor idler's fits control
(International Conference on Fracture, 2017)
The most common way to transfer tangential and axial loads in different types of assemblies is by interference fits. It is essential to determine interference fit parameters of pressed joints, which provides a proper ...
Temperature and time effects on fatigue strength of weldments
(International Conference on Fracture, 2017)
Temperature and service time effects on A-387 Gr. B Cr-Mo steel weldment fatigue strength have been evaluated. To assess service time effect on fatigue strength, samples are take from 40 years “old” material, whereas ...
Temperature and time effects on fracture toughness values in welded joint
(International Conference on Fracture, 2017)
Temperature and time effects on fracture toughness have been investigated for characteristic regions in a welded joint made of Cr-Mo steel A-387 Gr. B. Comparative analysis of fracture toughness values for characteristic ...
Numerical simulation of fatigue crack growth in welded pipes
(International Conference on Fracture, 2017)
Numerical simulation of fatigue crack growth has been performed by using the extended finite element method (xFEM) for modeling fatigue crack growth in a pipe made of API j55 steel by high-frequency welding. The obtained ...
Charpy and SEM investigation of Al-Mg friction stir weldments
(International Conference on Fracture, 2017)
Influence of friction stir welding processing variables on Charpy impact fracture behaviour of Al-Mg 5083 alloy was studied. Rotational and traversal welding rates were linked to the dynamic crack initiation and ductile ...
Fracture mechanics in Serbia - 49 years of development
(International Conference on Fracture, 2017)
Development of fracture mechanics in Serbia has been presented. To start with, it was the Magister thesis of Prof. Stojan Sedmak, 49 years ago (1968), as the first milestone. The stress concentration problems have been ...
Numerical analysis of fracture of non-standard ring specimen for examination of axially flawed cylindrical structures
(International Conference on Fracture, 2017)
Integrity of cylindrical structures, such as pipes and small-scale pressure vessels, is typically assessed by testing fracture mechanics specimens, like compact tensile CT or single-edge notched bending, SENB. However, ...
Creep crack growth - Comparison of two steel P91 and P22
(International Conference on Fracture, 2017)
The deformation and crack growth behaviour of P22 and P91 steel weldments tested at 550 °C and 600 °C, respectively,compact C(T) type specimens with sharp EDM starter notches in the base metal (BM) and heat affected zone ...
Fracture behaviour of S316L stainless steel thin plates
(International Conference on Fracture, 2017)
Experimental investigation was conducted on thin CT specimens made of S316L stainless steel, well known for good corrosion and reasonable fracture properties. Standard fracture mechanics testing is performed, and compared ...
A structural integrity model for hydrogen embrittlement of low carbon steel and the combined effect of help and hede mechanisms on macromechanical properties
(International Conference on Fracture, 2017)
A large number of contemporary studies about hydrogen embrittlement confirmed the multiple effects of hydrogen and activity of the different hydrogen embrittlement mechanisms in low carbon steels. However, critical evaluation ...
