Gurson-Tvergaard(GT) porous material model with optimized parameters and a practical void nucleation law is adopted to analyze deep drawing of cylindric parts.

Gurson-Tvergaard(GT) porous material model with optimized adjustment parameters and a practical void nucleation law were adopted to analyze the macroscopic stress-strain response,and according to the character of the metalforming processes,a unified fracture criterion,corresponding to different mechanisms of ductile fracture,tension-type mode and shear-type mode,was proposed.

Scattering of SH-wave around a circular cavity in half space;

In this paper,the dynamic response of an infinite circular cavity subjected to axially symmetric radial traction and fluid pressure in poroviscoelastic saturated medium is studied.

Scattering of SH-wave with arbitrary incident angle by a circular cavity in right-angle plane is studied together with its influence on seismic ground motion.

Critical load of rock salt roadbed with a spherical cavity

Based on previous theoretical models of cavity nucleation during creepdeformation, a new cavity nucleation model is proposed.
