the maximum tool effective stress is located in the flank face near cutting edge and the shear deformation zone on the workpiece.
最大刀具等效应力出现在前刀面上切削刃的周围,工件上最大等效应力出现在第一变形区。
there is a gradual decrease in tectonic superimposed hydrostatic pressure from compressional deformation zone through shear deformation zone to extensional deformation zone.
