Abstract

Assessment of lifetime under spectrum – fatigue loading was undertaken on GFRP composites material, using cumulative damage models proposed by Palmgren-Miner[1] Broutman & Sahu [2], Hashin & Rotem [3] and Epaarachchi & Clausen [[4]]. Non of the models were not performed well. Epaarachchi & Clausen [[4]] 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[4] model is performing better than the other models.
