摘要
利用材料的应力应变关系特性,参照强度稳定综合理论(CTSS)方法,推导出一种简单的计算公式来解决中厚简支板和球壳的极限强度问题。通过与有限元、规范、经验公式和试验的结果相比较,证明文中方法简单有效,可以指导工程设计。
A simple formula is derived to calculate the ultimate strength of simply supported plates and spherical shells by reference to stress and strain of the material properties and combined theory of strength and stability（CTSS）.Comparing the results of the finite element method,rules,empirical formula and experimental result,it is proved that the method is simple and validity to guide the engineering design.
