| 摘 要： | 本文以有限单元法研究了复合材料层合板、壳结构的承载能力,所采用的单元是考虑耦合效应的高精度的离散性克希霍夫（Kirchhoff）假定层合板和层合壳三角形单元,非线性迭代采用变步长的载荷增量法以及等刚度和变刚度相结合的交替迭代法,编制了计算机程序DDJ-FZJF,并以多例证明该程序和算法是有效的。

| Abstract: | The present paper deals with the loaded capability of laminated plate and shell structures using finite element technique. The finite elements adopted are triangular bending elements and shell elements with discrete Kir-chhoff hypothesis. The nonlinear iteration scheme employs variable load steps as well as constant or variable stiffness alternatively. A computer program DDJ-FZJF is developed and several computional examples are given. The numerical results show reasonableness of the method and effe-ctiveness of the compater program, |
