Abstract:

The rigid-plastic model of cutting problem is analyzed subject to a Coulomb-Mohr yield condition. The fields of stress, of strain and of deformation are investigated. Local continuation of stress field to rigid zones (the blank body and cuttings) is constructed. The existence region of full solution is detected and selection criteria of preferred solution is done. Depending of strain distribution and density changes in cuttings is given.
