Abstract
Thermoelastic stress analysis (TSA) is a well established technique for stress analysis.
Recent studies have revealed that the technique can be used to detect sub-surface defect effectively.
In this study, the technique has been used to examine the thermoelastic response to sub-surface
damage in simple bar specimens. The non-adiabatic thermoelastic response from areas close to the
damage has been studied. The study shows that the phase of the response along with the thermal
diffusion can provide a parameter that will help reveal subsurface stresses.
