Abstract

In this paper, a new analytical model has been presented for ENERGY ABSORPTION calculation of ALUMINUM-foam SANDWICH PANELs under high velocity impact. The panels consist of FOAM core sandwiched between two ALUMINUM skins. In analytical model, cylindrical rigid projectile with flat ended has been considered. In the quasi-static loading, by using the springs-mass model, ENERGY ABSORPTION of ALUMINUM skins with considering difference ENERGY ABSORPTION mechanisms has been calculated. Also FOAM absorbed a partial of projectile energy by crushing. ENERGY ABSORPTION of ALUMINUM-foam SANDWICH PANEL was calculated and energy balancing equation has been employed for determination the ballistic limit and residual velocity of projectiles. The results of ballistic limit and residual velocity computed by new model presented good agreement with experimental and numerical results. Also the effects of FOAM density, projectile mass and diameter in ENERGY ABSORPTION of SANDWICH PANEL has been investigated.
