A method of plasticity for general aligned spheroidal void or fiber-reinforced composites. (English) Zbl 0884.73035
Based on the general concept of the secant moduli method, together with a new way of evaluating the average matrix effective stress, we propose a method for nonlinear effective properties of general aligned fiber or void composites. The method is capable of predicting composite (especially for porous materials) yielding under a hydrostatic load.
