Resumen:
The work presented here establishes a procedure for the definition and interpretation ofan anisotropic constitutive damage model and it also allows extending the formulationto large strain. In this work is distinguished among natural anisotropy, due to thecharacteristics of the material, of that induced anisotropy by the constitutive modelduring the non-linear mechanical process. The space mapping transformation is appliedto solve the first kind of anisotropy and for the induced anisotropy, reason of this work,it is defined starting from an analogy with the kinematics problem of large strains. Thisidea helps to the formulation of the model using the parallelism that exists among thespace transformation in the kinematics of large strains and the space transformation inthe damage theory.
