FINITE ELEMENT STUDY OF VOID BEHAVIOR UNDER LOW STRESS TRIAXIALITY

Jixie qiangdu, 2017
Based on finite element simulation,a 3D cell model subjected to low stress triaxiality,with a spherical void located in center was developed. The distribution rule of stress and strain was investigated,as well as the developing trend of volume of void ...

The performance and prediction ability of advanced approach to ductile fracture [PDF]

, 2017
The present paper deals with the modelling of ductile fracture which is the result of severe plastic deformation under monotonic loading. It can be the result of a crash or accident or introduced intentionally. There is a need of increasing the safety in
