Abstract：Aluminum foam processes excellent performance of energy absorption. Sandwich panels have advantages in strength and rigidity. A contact blast with dose of 1.0kg was carried out to test the 100mm-thickness sandwich panel. The deformation and failure of the panel under contact blast loading conditions were investigated. The process of deformation and failure was researched by theoretical analysis and numerical simulation. Researches show that the aluminum foam-core sandwich panel consumed energy by local compression deformation and overall bending. The face sheets may be detached from the foam core. To reduce the deformation of the sandwich panel, it is effective to increase the thicknesses of foam core or face sheets. That way, the anti-blast performance of the sandwich panel will be improved.
