Stress-Strain Relations,did not involve the properties of the deforming material. It follows that all the derived equations are generalised and apply to any material although the primary consideration here will be confined to engineering metals. Two yield criteria for ductile metals were developed in chapter 4 so that it i

Plane Strain Plastic Deformation,e body of material. For many metal forming processes such as forging, drawing and rolling the geometrical configuration of the tooling, frictional conditions at the workpiece—tooling interfaces and the constraint of neighbouring material will result in the plastically deforming region being subject

Plastic Strain with Axial Symmetry,—perfectly plastic material. For some applications, allowance was made for the strain-hardening of engineering metals by means of a technological approach. The differential equations for force equilibrium and for strain-rate are .. This enables the method of the slip line field technique to be used
