Abstract: | This present paper dealt with bending deformation and failure behavior of sandwich and multilayer beams composed of aluminum foam core and metallic face sheets by finite element method(FEM) and four-point bending test.Results revealed that collapse of the multilayer beams is dominated by two basic modes:indentation(ID) and core shear(CS).ID is dominated by the maximum compressive strain and CS by the maximum shear strain.The failure of the sandwich beams depends on if the face sheets show ID mode in the mul... |
