Abstract：

In　this　paper,　the　failure　behavior　of　sandwich　beams　with　aluminum　foam　core　and　glass　fiber-reinforced　epoxy/aluminum　laminates　(GLARE)　face-sheets　under　three-point　bending　is　studied　by　experimental　and　numerical　methods.　Through　the　observation　of　the　experiments,　the　initial　failure　modes　of　GLARE　sandwich　beams　are　observed,　i.e.,　indentation　and　core　shear.　The　deformation　and　failure　process　of　GLARE　sandwich　beams　are　explored.　Finite　element　simulations　are　performed　by　using　ABAQUS　software,　and　the　numerical　results　agree　well　with　experimental　results　for　peak　loads　of　GLARE　sandwich　beams.　The　effects　of　geometrical　and　material　parameters　on　the　peak　loads　of　GLARE　sandwich　beams　are　discussed　in　details.　It　is　shown　that　the　peak　loads　and　energy　absorption　of　GLARE　sandwich　beams　increase　with　the　increase　of　face-sheet　thickness　and　foam　strength　and　the　decrease　of　span　length.　The　effects　of　elastic　modulus　of　foam　and　fiber　laying　angle　of　face-sheet　are　very　small.　©　2022　Elsevier　Ltd
