Dynamic Response of Aluminum Foam Sandwich Panel to Transverse Impact

Abstract:

The dynamic response of aluminum foam sandwich panels are studied experimentally by impacting the panels at mid-span with metal foam projectiles. Two types of core are considered: open-cell foam and closed-cell foam. By changing the launching speed of metal foam projectiles, different deformation/failure modes of sandwich panels are obtained. Strain history of face sheets in different positions is also recorded by strain gauges to observe its deformation mechanism. The experiment results indicated that when the strength of core is relatively small and the impulse exerted is large, erosion failure of front face and shear failure of core occurred.
