Resumen:
In this work a generalized anisotropic elastoplastic constitutive model for the large strain analysis of fiber-reinforced composite materials in the frame of the mixing theory and the finite element method is presented. The isotropic equivalent formulation proposed assumes the existence of a fictitious isotropic space where a mapped fictitious problem is solved. Both real anisotropic and fictitious spaces are related by means of linear fourth-order transformation tensors that contain the complete information about the real anisotropic material. Details of the numerical implementation of the model into a non-linear or large strain finite element solution scheme are provided. Application examples showing the performance of the model for analysis of fiber reinforced composite materials are given.
