摘要
本文尝试将损伤复合材料层板性能衰减研究扩展到含一般各向异性铺层的基体开裂层板·在第一部分中，采用分解刚度法处理法向与剪切响应的耦合问题，对承受面内载荷的对称约束开裂（θｍ／９０ｎ）ｓ层板，导出本构关系的近似解析解。
The study on property degradation of damaged composite laminates is extended to anisotropic laminates with matrix cracking. In (Ⅰ) of the paper, an idea of “stiffness patition” is proposed to deal with the puzzle that the in_plane normal response is coupled with the shear response of the laminates. For (θ m/90 n) s laminates containing transversely cracked layers under general in_plane loading,the constitutive relations are derived and the effective stiffnesses are expressed as the function of crack density.
