Abstract
In the present study we discuss two thermal methods, namely vibrothermography and thermoelastic emission (SPATE), for NDE of composite materials. Both methods take advantage of 'local resonance', i.e., independent flaw dynamics, to detect and evaluate damage. Complementary information about the flaw position, size and depth can also be obtained. These methods are fast, practical, and can be performed 'in situ'. The SPATE system can also reveal delaminations in relatively thick structural components.
