*Acoustic Emission - New Perspectives and Applications*

analysis. The temperature profile plotted at the defect interface signifies that the temperature rises drastically when the structure is excited with LDR frequency and subsequently, enhances the chance of defect detection using vibro-thermography technique. The vibro-thermographic imaging using an IR camera is recommended after longer period of LDR excitation. Thus, the LDR based vibro-thermography is found to be an efficient tool for detection, location and size estimation of defects in composite structures.
