TRANSPORTATION SYSTEM IMPACT LIMITER DESIGN USING RIGID POLYURETHANE FOAM

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.
