Inelastic Deformation of Sandwich Plates and Shells Under Dynamic Loading
Abstract
An investigation concerned with Inelastic Deformation of sandwich plates and shells under dynamic loading consisted of an experimental and an analytical study of the energy absorption capability of honeycomb and honeycomb sandwich structures. Laboratory tests of both types of samples were performed using both static loads and dynamic loads. The targets were attached to a ballistic pendulum arrangement either by a rigid backing or else by means of a simple support. Force-deformation curves were obtained by means of displacement and acceleration transducers. An analysis based on perfectly plastic behavior of the sandwich was obtained that permitted partial integration and hence minimized the computational procedure for the case of the backed sandwich; this was found to be in very good agreement with test results. Aluminum and Nomex honeycombs were employed as cores, while mostly aluminum face plates were employed, although polycarbonate, ABS and fiberglass materials were also investigated.
