This paper deals with experimental and analytical analysis of the mechanical behaviour of crushed foam cores. Three rigid cellular core materials are tested in uniaxial compression-tension-compression. An analytical model is proposed describing the stress-strain curve in tension and secondary compression. A special emphasis is laid on the relaxation behaviour of a crushed foam core in tension.
