Often shockwave experiments are described as vehicles for gathering Equation of State data, but typically only pressure and volume are recorded and temperature is almost always neglected.

Recently the SMF Group has been making significant progress with developing fast-response temperature gauges for use in shockwave experiments, the experimental results of which will be presented in a forthcoming colloquium (next term).

In addition to the measured experimental values it is also of interest to consider what temperatures are anticipated. In this colloquium the problem will be addressed for the polymeric material PMMA at two levels: using the extant indirect experimental data to estimate the temperature rises and secondly using Group Interaction Theory to predict the temperature rises.

Accurate and reliable experimental temperature data are necessary to fully constrain the EOS and thereby more fully inform and validate models of the same.
