Abstract
Shock loading experiments on graded, corrugated steel sandwich panels were conducted using a shock tube apparatus in combination with high speed digital photography and pressure sensors. Various combinations of multilayer corrugation cores were experimentally evaluated in order to understand the effects of gradation on the shock response of the corrugated panels. The results show that a gradual, linearly graded corrugation, from the thinnest corrugation on the front face to thickest corrugation on the back face, mitigates back face deflection of the panel the most, especially when normalized due to areal density. This arrangement leads to a novel sequential collapse mode that helps in the absorption of blast energy and thus reducing back face deflection.
