Hi,
From our documentation:Gurson's model is a plasticity model (TB GURSON) used to simulate ductile metal damage. The model is a micromechanics-based ductile damage model incorporating the void volume fraction into plasticity constitutive equation to represent the ductile damage process of void grow void nucleation and void coalescence. For more information see Gurson's Model in the Theory Reference for the Mechanical APDL and Mechanical Applications and TB GURSON command documentation.
