Anisotropía Inducida por Daño

Abstract

The study of damage induced anisotrophy has been subject of study in last years.
The prediction capacity depends on the macroscopic variable used to describe the underlying microscopic phenomenon. Generally, the models developed use vectors or second or fourth order tensors as damage variables.
A directional damage model obtained from a scalar damage model is presented in this paper. The model is based on the assumption that the solid is formed by a finite number of othotropic elastic fictitious components uniformly distributed in
the space. Each one of the components responds to scalar damage model based on the energy equivalence hypothesis. The resultant behavior of the solid is obtained through an homogeneization based on the the rule of mixtures.
