| Abstract: | 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. |

| Keywords: | cavity-sensitivity volume expanding cross-section deformation ratio |
