The use of closed cell foam sandwich structures in applications where a risk or impact or collision is increased leads a need to understand the dynamic behaviour of such materials. This work uses a specialised Instron servo-hyrdraulic test machine to apply intermediate strain rates to foam tensile dogbone specimens. The overall aim of this work is to provide a full thermomechanical characterisation of the foam material using digital image correlation (DIC) to measure strain, and infra-red thermography to measure temperature. This paper presents some initial strain data measured using DIC on images captured using a high speed camera. The results suggest a strain rate dependence when compared to the manufacturer's data sheet for quasi-static values.
