Available Relevant Study on Stress Analysis and Static Strength Prediction of Fiber Metal Laminates

Fiber metal laminates (FMLs) are a novel type of structural material that has been extensively applied in the aerospacefield. Theselaminates are sandwich-type composite materials that comprise alternate metal andfiber-reinforced resin layers. Because of thestructural characteristics of the material, it has high-impact resistance from the metal layer and increased fracture toughness andexcellent fatigue and damage tolerance properties from thefiber layer. To further develop and apply this new compositematerial, it is essential to understand the research status on the stress analysis of each component in FMLs and the tensilestrength properties of FMLs. Therefore, in this study, the current research status on the residual stress and applied stress of thecomponent materials in FMLs and the tensile strength of the laminates is summarized. The relationship between the appliedstress of each layer and the remote stress of laminates and the relationship between the tensile properties of laminates and thecomponent material properties in laminates are clarified. Additionally, the theoretical basis and direction of development of therelated models are analyzed and studied. Consequently, all of the above are aimed at laying a foundation for furtherinvestigations of the laminate theory and for the improvement of the theoretical research system.
