| 摘 要： | 基体开裂、纤维拔出、界面剥离等是碳纤维增强复合材料常出现的局部各向异性损伤现象,这些损伤逐渐扩展,削弱了材料的强度和刚度,影响材料的承载能力.对此利用宏微观摄动理论对位移进行双范围渐进展开,在微观位移中引入损伤应变,通过计算损伤应变集中因子,得到了含损伤的均质化损伤弹性常数(宏观有效刚度矩阵),用平均法和混合法检验了无... |

| Abstract: | Matrix cracking,fiber pulling out and interface debonding are the typical anisotropic damages for carbon fiber composites(CFC),which can degenerate the strength and stiffness,and decrease the loading capacity of CFC.In this paper,a macro-microscopic homogenized constitutive model with double-scale asymptotic expansion is established to analyze the mechanical behavior of CFC with anisotropic damage,and the homogenized elastic properties with the damage strain concentration factors are obtained,which are veri... |
