CAZACUTN
Description
3D Coupled damage law for porous hexagonal closed packed (HCP) materials exhibiting orthotropy and strength differential effect.
The model
The mathematical model was developed by (J. Stewart & O. Cazacu, 2011), where the CPB06 yield criterion is coupled with a phenomenological damage definition following a Gurson-type approach. The damage is modeled in the form of porosity ratio, and its evolution is ruled by phenomenological models of growth, nucleation and coalescence of voids. This constitutive law also integrates an automatic definition of coalescence onset, throughout the implementation of a Thomason-Zhang coalescence extension.
