Abstract
Initial work on combining Thermoelastic Stress Analysis (TSA) and Digital Image Correlation (DIC) is presented with the purpose of exploring their used in assessing defects in composite materials. TSA is usually performed using photon detector cameras that are expensive, a further objective of the paper is to investigate the capabilities of low-cost bolometer IR cameras for TSA. A carbon fibre reinforced polymer (CFRP) sample with artificial ‘waviness’ was created, so that a crack was developed inside the material. Both TSA and lock-in DIC methods detected the damage inside the CFRP specimen. Using the bolometer for TSA has highlighted the need for longer data capture times and the deleterious effects of other features associated with image capture that are inherent in the bolometer system.
