Abstract
In this paper, the new analytical prediction models were proposed for assessment of static strength and fatigue life of Fiber Metal Laminates (FMLs). The proposed static model combines composites mechanical linear-elastic behavior with non-linear elastoplastic behavior of metals, including curing stresses in laminae. Based on determined internal stress distribution through the thickness of the laminate, the fatigue life of FML is modeled at the lamina level, based on S-N mother curves of monolithic materials. The new criterion for prediction of residual fatigue life period in FMLs was proposed. Theoretical work was experimentally validated with good convergence of results.
