Internal crack detection and analysis using thermoelastic stress analysis
Internal crack detection and analysis using 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 with respect to that of the reference signal can be used to identify presence of sub surface defects, and may also be used to classify the defects.

Abstract
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 with respect to that of the reference signal can be used to identify presence of sub surface defects, and may also be used to classify the defects.
