An irreversible bilinear cohesive law considering the effects of strain rate and plastic strain and enabling reciprocating load

The commonly used bilinear cohesive law doesn’t consider the effects of strain rate and plastic strain, but it is well known that strain rate and plastic strain can greatly affect materials’ mechanical response. In this paper a new bilinear cohesive law is proposed that can handle these two effects and enables reciprocating load. Compared with the commonly used bilinear cohesive law, one difference in the new bilinear cohesive law is that normal...
