A Combined Isotropic-Kinematic Hardening Model for Large Deformation Metal Plasticity

Abstract

The need for increased accuracy in material modeling has been driven in recent years by advances in computing capability and the complexity of problems which now may be analyzed. Current material models are unable to represent many of the important multi-dimensional effects of the plastic deformation of metals to large strain. These effects can become very important at the level of deformation reached in metal processing operations, shear band formation, penetration mechanisms, and crack tip processes. An experimental program was conducted to produce a number of different types of tests on several materials. The types of tests included: tension, large strain compression, symmetric cyclic, unsymmetric cyclic, single reverse and large strain torsion. Materials tested were 316 stainless steel and 1100-0 aluminum. Also data for 3 carbon steels was analyzed. Keywords: Plastic properties, Plastic deformation, Metals, Stainless steel, Aluminum, Carbon steels, Mathematical models, Stress strain relations, Strain hardening.
