摘要
讨论了空洞敏感韧性及超塑性材料由于变形损伤引起的体积膨胀，提出了弹塑性有限变形下表征体积膨胀特性的横向变形系数在各向同性损伤条件下的解析表达式．
The volume expanding of cavity-sensitive ductile and superplastic materials induced by the internal damage of materials is studied.Under the condition of isotropic damage,a theoretical expression of the cross-section deformation ratio for elastic-plastic materials is proposed, which characterizes the volume expanding in elastic-plastic finite deformation.
