| Abstract Scope |
This presentation reviews the key features of a plasticity framework developed by the author and his co-workers over the last two decades. The purpose is to define an accurate macroscopic plasticity theory applicable to numerical simulations of practical forming processes in industry. The constitutive relationships are developed for anisotropic materials with an anisotropic hardening assumption. The framework relies on mathematical concepts, physical understanding of deformation mechanisms and experimental results. Lower scale simulation results are essential for the introduction of relevant features in the macroscopic framework. The experimental investigations on plasticity conducted by Professor Tozawa in the 1960’s and 70’s is of fundamental importance for the development and validation of the theory. An application of the approach for numerical forming process simulations of a complex sheet product is described as an illustration. |
