BEHAVIOUR OF CIRCULAR SANDWICH PANEL UNDER STATIC LOADING
Keywords:
Circular sandwich panel, PU foam, PVC foam (R55), failure modes.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 fo reach panel were determined. The relation between the observed damage
development, the property of degradation during the static lest of the panels was
investigated.
