RESEARCHES OF DIFFICULT PLASTIC DEFORMATION PROCESSES ON FLAT TRAJECTORIES OF VARIABLE CURVATURE

Abstract

The mathematical model of the temperatureplastics for describing the deformation processes on trajectories of any curvature is presented. Numerical researches of difficult plastic deformation of steel 9X2 on trajectories in form Arhimed's spiral, logarithmic spiral, astroida and the comparison of the received results with data of natural experiments carried out to determine applicability limitations of the model. It is shown that the presented model qualitatively and quantitatively describes main effects of difficult plastic deformation of metals for any nonproportional paths of temperature and force loading.
