摘　　要：利用高玉臣(1997)给出的非线性弹性大变形应变能函数,对橡胶类材料球壳受均布内压进行了大变形分析,得到了大变形求解方程。The non linear elastic strain energy function of large deformation given by Y.C. Gao (1997) is used to analyze a spherical shell of rubber like material compressed by uniform internal pressure. The final equilibrium equation of large deformation has been obtained, which reveals the non linear elastic character of rubber like material.
