RIGID-PLASTIC ANALYSIS OF CUTTING PROBLEM SUBJECT TO A COULOMB - MOHR YIELD CONDITION

Abstract

Rigid-plastic analysis of cutting problem with isolated slip line is done. Stresses on the slip line satisfy a Coulomb - Mohr yield condition. Stress field, velocity field and strain field are determined. Local continuation of stress field to a blank body and to cuttings is constructed. Full solution area is identified, the criteria of preferred solution selection is offered. The dependencies of strain distribution and density changing in cuttings are done.

Keywords: theory of plasticity, plain deformation, rigid-plastic body, cutting without fracture.
