Abstract
This paper presents the results of dynamic uniaxial-stress tests performed on polymer-foam material. A water-blown ester polyurethane foam designated as rigid and a castor-oil-base polyurethane foam designated as semirigid were tested in tension and compression at rates of loading from 10−3 in./in./sec to 103 in./in./sec at room temperature. A gas-operated medium-strain-rate machine was used for rates of loading from 10−3 to about 102 in./in./sec. Tests at higher rates were performed on a split Hopkinson-bar device. Highspeed photographic techniques were used to study dynamic fracture.
