Epaarachchi, Jayantha A. (2006) Assessment of damage accumulation in glass fibre reinforced plastic (GFRP) composites under spectrum fatigue loading. In: 2006 International Conference on Structural Integrity and Failure (SIF2006), 27-29 Sept 2006, Sydney, Australia.
Assessment of lifetime under spectrum – fatigue loading was undertaken on GFRP composites material, using cumulative damage models proposed by Palmgren-Miner Broutman & Sahu , Hashin & Rotem  and Epaarachchi & Clausen []. Non of the models were not performed well. Epaarachchi & Clausen [] model which is based on residual strength has the flexibility of applying according to assumed damage accumulation mechanisms. This model consistently predicting conservative lifetime while the other models almost over predicting. Further, a statistical analysis perform on predictions has shown that the Epaarachchi and Clausen model is performing better than the other models.
