Visual space modeling of the stress-strain state of profiled forgings

Abstract

We consider some methods of visual space modeling of the metal flow over the tool–workpiece contact surface and construct the diagram of contact stresses for the process of volume stamping of flat profiled blanks. The results obtained by different methods are characterized by good agreement. The proposed methods make it possible to predict form changes in the blanks and the formation of defects in the macrostructure of the deformed material, as well as to control the process of form changes in the forgings.
