Abstract
A cumulative fatigue damage model is presented for predicting the fatigue l ife of fibre-reinforced plastics (FRP) subjected to variable amplitude fati gue loading. It is assumed that the cumulative fatigue damage caused by the cyclic loading is proportional to the strength loss of FRP, and that the d amage state in laminates can be described phenomenologically by residual st rength. Some experimental results from two-stress level and block spectrums are employed to evaluate the model. Good coincidence between experiment an d theory has been obtained for GRP and CFRP.
