Abstract: This paper describes an optimization scheme for the J parameter calculation of cracks postulated in complex geometrical configurations such as elbow entries/exits and/or thickness transitions. The principle of this scheme ...

Abstract: Experiments have shown that ductile failure occurs sooner under cyclic loading conditions than under monotone ones. This reduction of ductility probably arises from an effect called “ratcheting of the porosity” that consists ...

Abstract: To predict fracture behavior for ductile materials, some ductile fracture simulation methods different from classical approaches have been investigated based on appropriate models of ductile fracture. For the future use ...
