Crashworthy behaviour of rigid polyurethane foam under constant impact energy
동일 충격 에너지 조건에서의 발포 폴리우레탄의 충격특성에 관한 연구

Abstract
Based on experimental impact testing data, due to changing of velocity and mass of the impactor simultaneously under constant impact energy, crashworthiness of polyurethane foam has been observed. Dynamic tests were carried out in an instrumented impact-testing machine. Also, modified Sherwood-Frost model was proposed to investigate the crashworthy behaviour of rigid polyurethane foam under the condition of constant impact energy.
