Techniques used to apply the finite element method to the analysis of rigid polyurethane foam that is confined by a thin, ductile metallic skin were investigated. The initial investigation covered the analysis of a simple geometry and loading condition of constrained and unconstrained foam using the constitutive relationships implied in the ''Elastic-Plastic'' and ''Crushable Foam'' material models in HONDO II and DYNA2D/3D. The final investigation consisted of the analysis of a series of tests of scale model impact limiters and comparison of the experimental and analytical results. 4 refs., 26 figs., 2 tabs.
