Abstract
AbstractThe particle finite element method (PFEM) combines the benefits of discrete modeling techniques and approaches based on continuum mechanics. It provides a convenient tool to deal with the problem of large configurational change, such as metal cutting, in which nonlinear plasticity plays a key role [1]. In this article we introduce a phenomenological plasticity model with the help of a multiplicative decomposition of the deformation gradient and an intermediate local configuration into the PFEM framework. Numerical examples of cutting simulations are presented to show the performance of the formulation.
