Abstract: The difference in the degree of plastic constraint in the vicinity of a pre-existing crack brings about difficulty in the evaluation of fracture performance of weldments when using fracture ...

Abstract: The processes of ductile fracture of KD32 steel specimens subjected to prestrain at elevated temperature are observed. Although several large voids are observed at a relatively small strain ...

Abstract: It is well known that fracture initiation behavior is influenced by weld thermal straining. In the present report, attention is focused on the influence of weld thermal straining on the fracture ...

Abstract: An analytical method for the assessment of failure probability of brittle materials exhibiting progressive cracking prior to cleavage fracture is presented. The underlying fracture mechanism is ...

Abstract: Fracture toughness tests of specimens in which the crack fronts consist of the weld metal region, the HAZ, and the base metal region have been carried out. It seems that, even in the case ...
