Abstract

Adhesive joints represent a valid alternative to classical welded and bolted methods, above all for composite materials in which the weight of structures plays an important role for designers. Defects such as debonding of adherents can compromise the correct static and dynamic behaviour of adhesive structures. In this regard, NDT techniques can be used for detecting and monitoring defects and damaged areas during the operative loading conditions. In this work, the capability of the Thermoelastic Stress Analysis (TSA) technique of monitoring debonding in adhesive T-joints has been investigated. Moreover, a quantitative comparison with the well-established Lock-in thermography and Ultrasounds techniques has been provided.
