Plastic behavior of sandwich beams with fiber metal laminate face-sheets and metal foam core: Combined local denting and overall deformation
Abstract In this paper, the plastic behavior of a fully clamped sandwich beam with fiber metal laminate (FML) face-sheets and metal foam core under transverse loading is analytically and numerically studied. Based on the modified rigid plastic model, the analytical solution for large deflection of FML sandwich beams under transverse loading is given, in which the local denting deformation is considered. Finite element results are conducted, and analytical solutions capture numerical results reasonably. The influences of material and geometrical parameters on the plastic behavior of FML sandwich beams are considered. The results show that the present analytical model can be used to predict the plastic behavior of fully clamped FML sandwich beams considering the local denting deformation.
Highlights Plastic behavior of sandwich beams with fiber metal laminate (FML) face-sheets is studied. A simplified formula for plastic behavior of FML sandwich beams is obtained considering local denting. Analytical solutions capture numerical results reasonably.
