摘要
本文利用参数拟二次规划法和非连续线弹性本构模型,构造了复合材料纤维/基体界面失效问题的细观力学模型并进行了有限元计算分析,得到了与实验相吻合的结果。
Based on the quasi-parametric quadratic programming method and discontinuous linear elastic constitutive law model, this paper constitutes the micro-mechanics model of failure process at the fiber-matrix interface and does numerical analysis by finite element. The calculated results show an agreement with that of experiment.
