Effects of Triaxiality, Strain Rate and Temperature on Damage Growth Law.
Ductile fracture occurs due to void nucleation, growth and finally coalescence into a micro-crack. In CDM model, the effect of void growth on material behaviour is incorporated by introducing a continuum variable, called damage, in the constitutive relation. The damage at a point represents the void density at that point. For the prediction of fracture, besides the damage-dependent elasto-plastic constitution relation, an evolution law for the void growth, called the damage growth law, is also needed.
