Abstract

Metal cutting is a very complex process of plastic deformation, and chip formation is a typical problem of large deformation, which involves the material nonlinearity, geometric nonlinearity and nonlinear state changes. Strain hardening model of Al 2024-T3 material is established based on elastic-plastic theory of material deformation. Finite element method is used in the analysis of the established model by ALGOR. The distribution of equivalent stress, yield stress and equivalent strain is concluded concretely in the metal cutting process in this paper.
