WebIn fact, one can actually define the ductile failure initiation curve for all triaxialities, which means that even shear and compression stress states (i.e., stress states that experimentally do not show failure mechanisms based on nucleation, growth and coalescence of voids) can be covered within the ductile initiation criterion. WebThe failure strain (displacement) can be specified as a function of temperature and/or predefined field variables. You can control how many cracks at a material point must fail before the material point is considered to have failed; the default is one crack.
