Abstract

Presented in the following pages is an experimental and numerical study of dynamic local buckling of skin on foam core. Impact tests on sandwich-type structures with skins stabilized by foam demonstrated that rupture appears by debonding of skins due to a local buckling phenomenon, and that the maximum stress in the skin, obtained at rupture, grows with the increase of the loading rate of the skin. A finite element analysis allows this phenomenon to be analyzed and understood, and a mass-spring-dashpot model is proposed to model the skin debonding initiation.
