Response of a Plain and Filled Elastomer (Solithane 113) to High Strain-Rate Compression, Shear, and Tension Loading

To quantify the high strain-rate mechanical response of plain Solithane, compression, shear, and tension experiments were performed under impact loading (microsecond time scales). Compression and tension measurements were carried out for filled Solithane containing 56.5 wt% of glass beads. The results show that the compression response (uniaxial strain) of plain Solithane is dominated by the mean stress-volume relation. The bulk modulus under impact loading is considerably higher than that determined from static measurements in the glassy state. The filled Solithane compression response can be approximated by a simple mixture theory using the Hugoniots of plain Solithane and glass.
