Abstract: Accurate modeling of workpiece material behavior in machining is critical to analyze and design a process. The workpiece material behavior in the machining process involves dynamic flow stress and damage/fracture behavior, ...

Abstract: A bifurcation analysis of forming limits for an orthotropic sheet metal is presented in this paper. The approach extends Stأ¶ren and Rice's (S–R) bifurcation analysis for isotropic materials, with materials following a ...
