with the data of Erlich et al. and Bull, indicating that the observed increase in cavitation threshold with increasing strain rate may be attributed to the greater viscous dissipation as the deformation rate is increased.

In contrast to the results quoted above, which indicated that the cavitation threshold of liquids may be determined by a heterogeneous nucleation mechanism, previous studies performed at high strain rates ($\dot{\epsilon}>$) have shown evidence that the spall strength of liquids is determined primarily by a homogenous cavitation mechanism. Carlson and Levine [@Carlson1975] used an electron beam to determine the spall strength of glycerol over a wide range of temperatures (491 to 623 K), where the viscosity changes by five orders of magnitude. The experiments showed a factor of eight decrease in spall strength as temperature was increased. [@Carlson1975] Utkin and Sosikov [@Utkin2010] used flyer-driven spall experiments to compare the effect of varying strain rate on the spall strength of liquids having vastly different viscosities: glycerol, hexane, methanol, and water. They observed that the spall strength in hexane, methanol, and water was nearly independent of strain rate over a range of approximately  [@Utkin2010], which was attributed to the weak dependence of the cavitation threshold on the
