This paper involves the development of an analytical/numerical crack growth model to predict surface and subsurface fatigue crack growth in the fibre metal laminate (FML) Glare subjected to combined tension and bending. The stress intensity factor for Glare can be divided into two parts: the stress intensity due to the crack opening stresses, and the stress intensity due to the fibre bridging stresses. The first component is derived from a ...
The fatigue crack growth properties of the laminated fiber-reinforced composite material arall(6) (arall 1 and arall 2) have been studied at low cyclic stress amplitudes and high numbers of cycles. a high frequency ultrasound resonance fatigue machine was used. the threshold stress intensity was determined by performing tests and increasing the stress amplitude stepwise. the threshold stress is proportional to the crack length. tests with constant cyclic stress amplitude were ...
