Abstract
In this paper, a generalized modeling and simulation framework is discussed to investigate heat generated at the crack surface during vibro-thermography. Modeling framework includes (i) a recently developed coupled thermo-elastic strainrate dependent heat generation model in the bulk of the material, and (ii) due to the clapping contact between the crack faces during vibro-thermography. Simulation results are analyzed considering a flat plate with a semi-ellipsoidal crack. Transient heat generation behavior near the crack region is analyzed. Dynamic contact models are used to capture the non-linear harmonics during crack interaction and its contribution towards heat signature. Simulation results are obtained by incorporating the model in a finite element scheme.
