Analysis of deformation and damage evolution in hot elongation forging

Abstract

The paper describes the analysis of the three-dimensional stress and strain state for the process of elongation forging of the X37CrMoV51 die steel using the finite element method. The results of simulation studies of the metal flow pattern and thermal phenomena in the hot forging process carried out in three different forging tools are reported. The results of the studies have been complemented with the prediction of the occurrence of ductile fractures during forging. The numerical analysis was performed using the DEFORM-3D program. The comparison of the theoretical study and experimental test results indicatesapossibility of applying the developed model to the examination of strains and prediction of material fracturing during the hot forging of die steel.
