摘要：
In this study, mechanical properties of three types of polymeric foams (polypropylene (PP), polysyrene (PS) and polyurethane (PU) foams) are investigated for impact-contact simulation. Focus has been placed on the strain rate and temperature effects. Based on selected experimental results from uniaxial compression, hydrostatic compression, and simple shear tests, phenomenological hydrodynamic elastoplastic constitutive law is developed to model these polymeric foams for impact simulation of dummy models.
