Micromechanics of nonlinear composites

Two homogenization methods are presented for modeling the overall elasto-plastic behavior of composite materials, the first one is applied to the case where the nonlocal property of the constituents can be neglected, and the second one considers this nonlocal effect by idealizing the constituents as micropolar materials. The secant moduli method and Ponte Castan?eda's variational method are discussed in these two homogenization methods.EI0I35-42274-27
