The Parameters of the Stress State in the Operations of Plastic Deformation

Article Preview

Abstract:

The invariant characteristics of stress state arising on the sheet metal forming operations are considered. Using the trigonometric presentation of stresses, the stress state is constructed. In this case the trajectories of principal stresses are presented by the help of the arcs of circles, that confirms the nonmonotonicity of the processes of deformation.
