摘要
Motivated by experimental observations, the shear-lag method has been employed to model the competition between the transverse cracking and delamination modes of failure that occur in cross-ply AS4/3501-6 carbon-fibre/epoxy coupons subjected to fatigue. The results explain the extensive delaminations and reduced crack densities that arise under immersed fatigue conditions, as compared with fatigue in air. (C) 1999 Elsevier Science Ltd.
