SUMMARY:Challenges in capturing transient thermal evolutions in materials 
 using IR imaging - Janice Barton & Karthik Ramakrishnan\, School of Civil\
 , Aerospace and Design Engineering\, University of Bristol

DESCRIPTION: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 move
 s on to cover some preliminary work on the application of Telops Fast m3K 
 infrared photon detector thermal camera for strain energy release rate mea
 surement in fibre failure of carbon fibre composites and during high strai
 n rate loading. It is shown that thermography can be used to identify the 
 crack propagation and crack lengths using local changes in temperature nea
 r the crack tip in a compact tension specimen.
