PHYSICO-PHENOMENOLOGICAL MODEL OF METAL RESISTANCE TO PLASTIC DEFORMATION FOR THE CALCULATION OF THE PROCESSES OF METAL PLASTIC WORKING. PART 2. PARTICULAR CASES OF THE MODEL AND ITS EXPERIMENTAL VALIDATION

摘要

Particular cases of the model with reference to cold, warn, and hot deformation conditions have been considered. Parameters of the model have been determined by means of experimental stress-strain curves. For a group of low-carbon, medium-carbon, and low-alloy steels, it has been shown that the proposed model describes satisfactorily resistance to deformation in a wide temperature and strain-rate with allowance for the effect of the loading history, which is related to the strain-rate time dependence.
