Abstract

In order to obtain mechanical properties of EPDM material under different strain rates, static and dynamic compression experiments were completed by using a universal testing machine and split Hopkinson pressure bar (SHPB) device in this paper, and availability of the dynamic experimental data was examined. Based on stress-strain curves of EPDM material under different strain rates, it can be found that EPDM is a rate sensitive material, when producing the same deformation, the corresponding stress increases with the increase of strain rate, but when reaching a certain high strain rate, the strain rate sensitivity decreases. In addition, the hardening phenomena happen when EPDM is deformed in large strain, and the increase of the stress becomes larger.
