Simulation of 42CrMo Billet Forging and its Defects Analyses During Forming Process Based on DEFORM-3D

摘要

By means of commercial and professional plastic forming software DEFORM-3D, the forging process of 42CrMo billet was simulated. It is concluded that (1) the changes of the temperatures, stresses and strains at the different regions of the billet were simulated during the entire forging process, (2) based on the stress and strain distributions of the forged billet, the forming defects analyze was proceeded and it is concluded that some forging defects or flaw may occur near the head surface or around the side edge during the plastic deformation process.
