Dynamic mechanical behavior and constitutive relationship of rubber fiber concrete after high temperature

Dynamic mechanical behavior and constitutive relationship of rubber fiber concrete after high temperature

Abstract To investigate the effect of temperature on the dynamic mechanical properties of rubber–polypropylene fiber concrete (RPFC), dynamic mechanical parameters and energy parameters of RPFC at different temperatures were obtained using the Split Hopkinson Pressure Bar (SHPB) test. Subsequently,...
