摘要
本文介绍适用于复合材料（含各向同性材料）层合加筋板壳结构的后屈曲强度及破坏分析的程序系统（ＣＯＭＰＯＳＳ程序系统）的功能特点、原理和结构，通过一个受压剪载荷作用的加筋层合矩形板的破坏分析，并与试验结果作了比较，说明该程序系统的正确。
The programming system of postbuckling strength and failure analysis for composite stiffened plate and shell structures is generatly introducted in the paper.The function and the characterist,the theory and the structure of this program are also presented.Finally through the comparison of calculating and experiment resuls for a composite stiffened rectangle plate under the compreseive.shear loading,the correcty and the reliability of programming system are verified.
