摘　　要：对具有幂硬化塑性剪切界面层效应的复合材料桥联进行断裂力学分析，得到了桥联增韧和裂纹张开位移的控制方程，并按照非线性Ｖｏｌｔｅｒｒａ型积分方程的迭代解给出其数值结果。并详细讨论界面相参数对桥联效应的影响。A fracture mechanics analysis of the crack-bridging in an uniaxially fiber reinforced composite ispresented. The integral equation governing bridge-toughening as well as crack opening displacementCOD) for the composite with a power law hardening plastic interphase are constructed based on thereference [2]. Numerical results of the COD equation etc. are obtained by means of iteration-solutionmethod of the nonlinear Volterra integral equation. The effect of inter facial parameters on the toughening of composite crack-bridging is discussed in detail.
