Research on Dynamic Mechanical Behavior of Silicon Rubber Under Different Temperatures

MIN JIAO, MINGFENG TANG, HE YANG, LINGANG LAN

Abstract


By use of split Hopkinson pressure bars(SHPB) technique with temperature controllers, a kind of silicon rubber is investigated for understanding its dynamic constitutive behaviors at high strain rates (740-1740s-1) and different temperatures (-40℃, 20℃, 80℃). Experimental results show that silicon rubber is strain-rate sensitive and shows viscoelastic characteristics at room temperature. Moreover this kind of silicon rubber is temperature sensitive at the same strain rate, but is not strain-rate sensitive at high or low temperature.
