Challenges in capturing transient thermal evolutions in materials using IR imaging

If you have a question about this talk, please contact Stephen Walley .

The presentation starts with an overview of progress in using both photon detector and bolometer IR camera types in capturing transient thermal evolutions. The prospects for using very low-cost thermal cameras in material evaluations is discussed in detail. The presentation then moves on to cover some preliminary work on the application of Telops Fast m3K infrared photon detector thermal camera for strain energy release rate measurement in fibre failure of carbon fibre composites and during high strain rate loading. It is shown that thermography can be used to identify the crack propagation and crack lengths using local changes in temperature near the crack tip in a compact tension specimen.
