摘要
本文利用Ｓｔｒｉｃｋｌｉｎ法￣［５］，采用三角形单元推导出了板在考虑弯曲和膜薄力的共同作用下的非线性单元刚度矩阵的计算公式，还以此编制了壳体大挠度问题的计算程序，进行了算例分析，与有关文献作了比较。
Using Stricklin Method￣[5] we have in this paper derived the formulas for the generation of non-linear element stiffness matrix of a triangle element when considering both the bending and the in-plane membrane forces. A computer pro-gramme for the calculation of large deflection and inner forces of shallow shells is designed on these formulas. The central deflection curve computed by this pro-gramme is compared with other pertaining results.
