Paper Title:
Yield Criterion and Constitutive Model for Ductile Materials with Hydrogen and Deformation Induced Voids
  Abstract

Using the method of mesomechanics, a represent volume element (RVE) with internal pressure acted on the inner wall of the void is suggested to simulate the hydrogen induced cracking (HIC) in porous ductile materials. Based on this RVE, yield criterion is derived and constitutive model is constructed. Simulations show that the hydrogen pressure intensively reduces the yield stress for porous ductile materials
