Paper Title:
Simulation of Void Defect Evolvement during the Forging of Steel Ingot
  Abstract

Simulation method of void defect evolvement during the forging of steel ingot was determined by comparing simulated and experimental results of void closure in the cylinder specimens during forging. Calculation results of long and short void defect evolvement during forging indicated that effective strain required for void closure was induced by the integration of stress. The closure of tetrahedral void is the most difficult with the maximal values of critical reduction on void closure during forging, on the basis of which, theory basis is provided for making forging process.
