在广义自洽有限元迭代法￣［１］的基础上研究了损伤界面对多相复合材料的总体平均横向力学性能的影响。给出了对于不同体分比和损伤界面性质的典型复合材料的数值结果。数值分析表明损伤界面的厚度及其损伤程度对复合材料总体平均横向平面应变体积模量和剪切模量有显著影响。本文还计算了损伤界面区域的局部应力场。
Based on the generalized self-consistent finite element method [1], the effect of interface damage on the overall average transverse mechanical properties of multi-phase composites was investigated. The numerical results of typical composites with different volume fraction and interface properties are given. Numerical analysis shows that the thickness of the damaged interface and the degree of damage have a significant effect on the overall average transverse plane strain bulk modulus and shear modulus of the composites. We also calculate the local stress field in the damaged interface area.
