A Numerical Study on Response of Foam Sandwich Beams with Corrugated Skins Subjected to Large Deflection

Abstract

Foam sandwich beams with sine-curve skins subjected to large deflection were studied using finite element analysis, in which damage mechanisms of face sheet were introduced. Sandwich beams with various sinusoidal skins were simulated and results indicated that corrugation could make the deflection and energy absorption up to face fracture increase remarkably compared to the counterpart with planar skins.
