| Abstract: | 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. |
