The crush behaviour of Rohacell-51WF structural foam

Various mechanical behaviours of Rohacell-51WF foam are studied in the pres ent paper. Uniaxial tension and compression, and pure shear properties are obtained using standard test techniques. A hydrostatic test rig was designe d to conduct hydrostatic compressive tests on the foam. These material test s give basic mechanical properties of the studied foam. Transverse shear ef fects on the compressive behaviour of the foam are studied by developing a shear-compression test technique. Deformation and failure features during f oam crushing are discussed according to experimental evidence. (C) 2000 Els evier Science Ltd. All rights reserved.
