Abstract
A finite strain theory for anisotropic elastic-plastic materials is presented. The example of a metal-matrix composite reinforced by aligned fibers is analyzed in detail. The plastic spin W p, which is the average spin of the continuum as seen by an observer spinning with the substructure (fiber), is shown to be W p = nn⋅D p-D p⋅nn, where D p is the plastic part of the deformation rate, and n is the unit vector in the direction of the fiber. The numerical implementation of the developed model is briefly discussed and the example of finite simple shear is presented.
