Numerical simulation for studying constraint effect on ductile fracture initiation using complete Gurson model

Numerical simulation for studying constraint effect on ductile fracture initiation using complete Gurson model

Ductile fracture initiation in high-strength low alloyed welded steel joints is predicted using micromechanical complete Gurson model (CGM). The crack tip constraint and variation of stress triaxiality in ligament are considered on single-edge notch bend SE(B) and compact tension C(T) specimens, inc...
