Abstract
An extension of an anisotropic damage model is proposed to take into a ccount the crack closure phenomenon and elastic moduli recovery. Our a pproach is built on a micromechanical analysis and leads to the introd uction of a fourth-order parameter which controls damage activation/de activation and does not require further information with respect to th e basic version of the model. The emphasis is put on continuity of the stress-strain response.
