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 ...
Application of Complete Gurson Model for prediction of ductile fracture in welded steel joints
(Trans Tech Publications Ltd, 2009)
Ductile fracture process includes three stages: void nucleation, their growth and coalescence. The voids nucleate due to the fracture or separation of non-metallic inclusions and secondary-phase particles from the material ...
