A Plasticity Framework for Forming Applications

Abstract

This presentation reviews the key features of a macroscopic plasticity framework 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 1960s and 1970s is of fundamental importance for the development and validation of the theory. ? 2021, The Minerals, Metals & Materials Society.
