本文将含有变形损伤的本构关系引入刚粘塑性有限元程序,用于超塑性胀形的数值分析,讨论了应变速率敏感性,孔洞长大及静水压对极限成形应变的影响,并与文献发表的实验结果进行了比较。
In this paper, the constitutive relation of deformation damage is introduced into the rigid visco-plastic finite element program for the numerical analysis of superplastic bulging. The effects of strain rate sensitivity, hole growth and hydrostatic pressure on the ultimate forming strain are discussed. Literature published experimental results were compared.
