Behaviour of circular sandwich panel under static loading

Abstract

In this paper, the performance and behaviour of the circular sandwich panel under static loading was examined. The circular sandwich panel was centrally loaded by using hemispherical and flat indenters on their respective support units. The panel materials used specifically for this project are mild steel skin and PVC foam namely R55 and polyurethane (PU) foam cores. The aim of this study is to obtain experimental evidence of the failure modes of the circular sandwich panels under concentrated load at the centre of panels, simply supported around the edge corners for the panel. After static tests, the whole curves for each panel were determined. The relation between the observed damage development, the property of degradation during the static test of the panels was investigated.
