Abstract

The modified viscoplastic Taylor model proposed recently by Parks and Ahzi (1990, J. Mech. Phys. Solids 38, 701) for crystals possessing less than five independent slip systems is re-formulated. The proposed formulation can be applied to study the plasticity and texture evolution in crystals possessing five or less than five physically distinct and independent slip systems. This formulation has the advantages of providing explicit solutions and of not having to explicitly identify the kinematic constraints associated with the insufficient number of independent slip systems. This model is employed to simulate the plane strain compression of idealized 100% crystalline poly(ethylene terephthalate). Predicted crystallographic textures are in excellent agreement with experimental results. This example illustrates one of the many applications of this new formulation of the modified Taylor model.
