DOUBLE SCALAR FORMULATION OF ISOTROPIC ELASTIC DAMAGE

Description of damage state and damage evolution are of fundamental importance that have not been completely resolved This paper focuses on a most simple case, i e , isotropic elastic damage for initially isotropic elastic materials We note some limitations of the classical isotropic damage theory based on the strain equivalence hypothesis, in which the damage state is described by a single scalar damage variable In the present paper, it is shown that the complete description for isotropic elastic ...
