摘要: Abstract Uniaxial tensile tests have been carried out to accurately evaluate the in-plain mechanical properties of fiber metal laminates (FMLs). The FMLs in this paper comprised a layer self-reinforced polypropylene (SRPP) sandwiched between two layers aluminum alloy 5052-H34. In study, nonlinear and fracture behavior under in-plane loading conditions has investigated with numerical simulations theoretical analysis. simulation based on finite element modeling using ABAQUS/Explicit constitutive model volume fraction approach rule mixture modified classical lamination theory, which incorporates elastic–plastic SRPP, are used predict such as stress–strain response deformation FMLs. addition, pre-stretching process is reduce thermal residual stresses before uniaxial Through comparing analysis experimental results, it concluded that adopted can describe sufficient accuracy actual curve.
