Abstract
The effect of a short duration cyclic overload on the residual life and str ength of laminated glass-fiber reinforced polyester is studied. A uniaxial tensile fatigue loading with the sti ess ratio 0.1 is considered. The resid ual life of the composite decreases dire to the overload, while the residua l strength is almost unaffected. A reasonable agreement of experimental dat a, with the prediction by a residual strength model and by Miner's rule is observed.
