| Abstract: | This paper presents a theoretical formulation of fiber bridging constitutive laws under monotonic and cyclic loading with the effect of interfacial bond degradation. A bilinear interfacial bond degradation function is introduced with accumulated crack opening displacement change. This parameter accounts for the damage history, which could be different at each location on the surface of a growing crack. With the interfacial bond degradation function, the analytical expressions of fiber bridging stress-crack opening displacement ( σ_ f - δ ) and fiber bridging stress amplitude -crack opening displacement amplitude ( Δσ_ f - Δδ ) relation are obtained. Two sets of comparisons lead to similar degradation functions, which supports the validity of the presented interfacial bond degradation function with accumulated crack opening displacement change. |
