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 ...
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 ...
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 ...
