ENERGY ABSORPTION AND IMPACT BEHAVIOR OF STIFFENED AND UNSTIFFENED ALUMINUM PANELS

The impact behavior of stiffened and unstiffened square aluminum panels under fixed boundary conditions was investigated experimentally and theoretically, and the ultimate energy-absorbing characteristics were determined as a function of geometry. The effect of rigid, closed-cell foam (2-lb/cubic foot urethane) on an unstiffened panel was also investigated. A geometric scaling law was developed to extrapolate experimental results to sizes needed for the underbody collision protection system of surface effect vehicles for Arctic operation. Protection levels were determined as a function of allowable vertical impact velocity and craft weight.
