Blast resistance of stiffened sandwich panels with closed-cell aluminum foam

In the present investigation, response of the stiffened sandwich foam panels with closed-cell aluminum foam cores subjected to blast load is examined. The panels have the metal foam sandwiched between two steel sheets. To improve resistance of the sandwich foam panel against blast, stiffeners are provided and their dynamic response under varying blast load is studied. Blast load is applied using blast equations available in LS-DYNA which takes into account reflection of blast from surface of the sandwich foam panel. Finite element based numerical simulations for dynamic analysis are performed ...
