| 摘 要： | 分析了弹性薄球壳之间及其与刚性板之间的接触大形变问题。文中将大挠度非线性同题转化为一系列小挠度线性问题来求解,方法简单而有效。对两种接触系统的载荷与位移关系进行了一系列实验,理论与实验结果相当符合。

| Abstract: | This paper presents an analysis of the mechanical behavious of a thin elastic spherical shell contactcd with: (1) a rigid plate; and (2) another shell of the same size and material. The large deflection problem is treated as a series of small deflection problems. The method is simple and effective. A number of experiments were made, and the results show that the theoretical relationship between compressive load and displacement agrees well with experimental one. |
