Conference paper


The science of thermoelasticity is a study of the coupling phenomenon between thermal energy and mechanical deformation in elastic materials. The non-contacting investigation of the thermoelastic effect using infrared technology was first reported in 1967 by Beigen [1,2]. This technology has developed to a stage where highly sensitive array detectors are now widely used for thermoelastic stress analysis (TSA) and a variety of thermographic and thermal NDE studies[3]. Array systems such as the DeltaTherm system may be used to obtain full-field maps of the minute differential temperature on the surface of a component due to the thermoelastic effect, In addition, these systems are also capable of providing static thermal images of the absolute temperature of the component at the time the image is captured.
