Simulación de Procesos Multidisipativos a través de la Teoría de Mezclas

Bibiana M. Luccioni, Pablo E. Martín


The greater part of the materials, in particular geomaterials, presents a non linear behaviour which is usually the consequence of multiple sources of energy dissipation.
Most of them also presents a strongly directional response.
In this paper, the application of the mixture theory to the simulation of the mechanical behaviour of multidisipative anisotropic materials is presented. Mixture theory, normally
restricted to model multiphase composites, is applied, in this case, to combined different types of energy dissipation and to model anisotropy. In this way, a great range of behaviours can be simulated starting from elastic anisotropic models, pure isotropic plasticity models or pure isotropic damage models.
