摘要: 一、引言 为了给飞行器的设计提供理论依据,采用力法分析了不同材料的受压固支、简支正交异性矩形分层模型的屈曲和后屈曲,把一组非线性偏微分方程构成的边值问题化为求解一组非线性代数方程,进而用梯度法解之,最后给出有关的计算结果,并说明了支承条件的影响。

Abstract: The delamination in a laminate will buckle under a sufficiently large in-plane compression.The problems of buckling and po- stbuckling of clamped and ' simply supported orthotropic rectangular delaminatioa for different material properties; under compression have been solved by means of the force, method in this paper. Some nume-rical results are given.
