    Notizen: Summary Based on suggestions given in [1], the uni-axial compressive stress-strain relations for elastomeric foams, which were developed in [2], have been extended to cover the bi- and tri-axial stress modes of compression for both open- and closed-cell elastomeric foams.The stress-strain relations for uni- and tri-axial stress compression modes were validated by comparing numerical predictions, which were based on them, to experimental results.

    Notizen: Abstract The equations governing the flow resulting from a head-on collision between a normal shock wave and a rubber-supported plate are listed. The non-dimensional parameters that may affect the resulting flow are specified and their influence on the post-collision flow and waves is studied numerically. It is shown that changes in: the area-ratio between the gas and the rubber cross-sections, the incident shock wave Mach number and the mass ratio between the rubber and the plate it supports, all have significant effects on the post-collision gas and rubber responses. Changes in the rubber elasticity constant also affect the post-collision flow. The extent of the effect that changes in the above mentioned parameters have on the post-collision flow responses depends upon the loading mode used. Three different modes were studied; uni-axial stress loading, bi-axial stress loading and uni-axial strain loading.

    Notizen: Abstract In the Part I of this study, namely the analytical part in Mazor et al. (1992), the governing equations of the phenomenon in which a planar shock wave collides head-on with a cellular material and interacts with it were developed using a Lagrangian approach. In addition, the numerical approach adopted by us during the numerical course of this study was briefly outlined there. The present part reports on experimental and numerical results of the head-on reflection of a planar shock wave with an open cell polyurethane foam. Foams as mentioned by Gibson and Ashby (1988) and summerized in Part I of this study by Mazor et al. (1992), are one of the two general types of cellular materials.

    Notizen: Abstract The equations governing the head-on collision of a planar shock wave with a cellular material and a numerical scheme for solving the set of the governing equations were outlined. In addition, the condition for the transmitted compression waves to transform into a shock wave, inside the cellular material was introduced. It was proved analytically that a cellular material cannot be used as a means of reducing the pressure load acting on the end-wall of the shock tube. In subsequent papers, the interaction of planar shock waves with specific cellular materials, e.g., foams and honeycombs will be described in detail.

    Notizen: Abstract Well tailored compressive stress-strain relations for elastomeric open and closed cell foams under a uni-axial stress compression were developed. These sets are aimed at replacing those presented by Gibson and Ashby (1988) [1] since they are mismatched and cannot be used. The proposed set of compressible stress-strain relations for elastomeric open cell foams was compared with experimental results. Good agreement was seen.
