Abstract: Theoretically predicting the service life of the Fiber Reinforced Polymer (FRP) laminates is important to design safe structural components. In common, failure of FRP laminates includes fiber/matrix cracking, delamination of fibers, debonding of reinforcement materials, and matrix failure due to stress gradients. Conventionally failure envelops of the FRP laminates are strongly depends upon maximum stress criterion and normal strain criterion. This review paper reveals the all the failure prediction theories based on stress and strain induced in laminates. This article covers the recent well established failure prediction theories and common modeling approaches of fiber reinforced polymer composites.
Keywords: Service life, Failure theories, Laminates, Stress criterion, Strain criterion.
