Abstract:

This project made major contributions to our overarching research goal that the response of low modulus materials to deformations at high strain rates be predicted from experiments per-formed exclusively under low rate loading. In particular, we produced experimental data and modelling frameworks that demonstrate the feasibility of that goal. Further, we designed novel methods for direct measurements of the high rate response, enabling, for the first time, high frequency shear moduli to be measured experimentally. These developments are important for better use of low modulus polymer materials, for example in polymer bonded explosives, pot-ting compounds for protection of electronics in extreme environments, and personal protective equipment. They also have significance for testing of biological materials.
