Fatigue damage mechanics of composite materials part IV: prediction of post-fatigue stiffness

Spearing, S.M., Beaumont, P.W.R. and Smith, P.A. (1992) Fatigue damage mechanics of composite materials part IV: prediction of post-fatigue stiffness Composites Science and Technology, 44, (4), pp. 309-317. (doi:10.1016/0266-3538(92)90068-E).

Record type: Article


A model has been developed for predicting the stiffness of cross-ply carbon fibre composite laminates containing a notch from which damage, in the form of matrix cracks, splits and delaminations, has grown. A combination of experimental and theoretical results have been used to deduce appropriate degraded stiffness properties for the damaged regions of the laminate. These degraded stiffnesses have then been incorporated into a finite element representation of the notched laminate to predict the overall stiffness. Agreement with experimental data is satisfactory.
