用边界元方法对横向载荷作用下纤维增强复合材料界面的滑移进行分析。通过离散边界,首先分别得到两组纤维物和基体的线性代数方程,然后结合界面条件可以导出最终的系统方程,其中界面的模拟采用弹簧阻力模型。给出的数值算例表明所提出的方法是有效的。
The boundary element method is used to analyze the slippage at the interface of fiber reinforced composites under transverse load. Through the discrete boundary, the linear algebraic equations of two kinds of fibrous materials and matrixes are obtained respectively. Then the final system equations can be derived by combining with the interface conditions. The simulation of the interface adopts the spring resistance model. Numerical examples are given to show that the proposed method is effective.
