Heat and work distributions are computed from synchronized temperature and strain fields obtained by infrared thermography (IRT) and digital image correlation (DIC). The DIRC data acquisition and processing are described in the first part of the article. Then, we show the relevance and usage of DIRC by employing it to characterize the cyclic evolution of the thermomechanical response of a superelastic NiTi wire single bondtermed functional fatigue. Particularly, we evaluated the evolution of the heat, work, and internal energy changes upon the repeated propagation of stress-induced martensitic transformations (SIMTs) shear-bands, producing a highly heterogeneous deformation scenario.
