Abstract
The effect of mode mixty on fatigue crack growth behavior from delamination was investigated with UD laminates (made of unidirectional laminates) and C laminates (made of unidirectional laminates and cloth laminates) of high strength glass fiber reinforced plastics (GFRP).Fatigue crack growth tests were carried out by mixed mode bending specimens at a stress ratio of R=0.1. In UD and C laminates, the crack propagation rate da/dN decreased as mixed mode ratio GI max/GT maxdecreased when compared at the same total maximum energy release rate GT max (=GI max+ GII max). At a constant crack propagation rate under mixed mode loading, the driving force is expressed in terms of a linear combination of the pure mode I GI maxand the pure mode II GII max. The G T max in C laminates approached the GT maxin UD laminates as GI max/GT maxincreased at the same crack propagation rate. In UD and C laminates, fiber bridging took place at GI max/GT max=0.70 and the crack propagation rate was expressed by a power function of the maximum value, GT tip max, of the energy release rate at the crack tip. Fractographic observation UD and C laminates showed that the crack propagation path was on the surface of fibers at GI max/GT max≤0.41 and some resin facture was observed at GI max/GT max=0.70.
