## Abstract The mechanical response of integralβskin rigid polyurethane foam, with an average density of 300 to 700 kg/m^3^, to constant rate and creep loading was determined. Sandwich specimens were modeled by layers of a core material and two skins, whose secant moduli had been determined experim
