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·对第（Ⅰ）部分提出的分解刚度法给出分解刚度值确定方程，完整了开裂层板本构关系解；对（θｍ／９０ｎ）ｓ开裂层板刚度衰减进行了数值计算并对计算结果进行了讨论·
he study on property degradation of damaged composite laminates is extended to anisotropic laminates with matrix cracking. In (Ⅱ) of the paper, a solution for partitioned stiffness is given to complete the constitutive relations developed in (Ⅰ). The stiffness degradation in (θm/90n)s cracked laminates is calculated and the results are discussed.
