Abstract
This paper describes work in which stress-strain data is obtained for samples of PMMA and PS during deformation at strain
rates in the range 10
-4 to 10
3 s
-1 at temperatures in the range 293 K to 363 K. The effect of strain rate on the
-transition of PMMA and PS is also studied over a range of temperatures but a limited strain rate range. The relationship
between strain rate and activation energy and volume is obtained by applying Eyring theory to the PMMA stress-strain curves
at their yield point.
