The Mechanical Behaviour of Foam-filled Corrugated Core Sandwich Panels In Lateral Compression

A series of experimental investigations and numerical analyses is presented into the compression response, and subsequent failure modes in foam-filled corrugated core sandwich panels. The corrugated cores based on carbon fibre reinforced plastic (CFRP) and glass fibre reinforced plastic (GFRP) were...
