In this paper is presented a general mixing theory applied to the numerical simulation of multiphase composite material behavior. This theory is based on the mixture of the basic substances of the composite and allow evaluate the inter-dependence behavior between the different compounding constitutive models for n-phases composite materials. Also, the initial anisotropy of each compounding is treated in the present work by mean of a mapped isotropic plastic formulation. This allows classic isotropic plasticity theory to be applied to orthotropic or anisotropic materials. Examples of application show the good performance of the mixing anisotropy theory for the simulation of bulk composite materials.
