摘要：

Inside a large displacement, rotation and strain finite element framework, a damage model is proposed to take into account the microvoid volume fraction increase in the constitutive matrix. The corresponding formulations are described. The damage model is applied to compute the porosity evolution during the multi-step hot forging of tubes.
