3. Conclusion

The results presented in this article have confirmed that the dissipativity of materials tested under load is indeed a sensitive and precise manifestation of their state of damage. The change in the dissipative regime is sufficiently contrasted to allow (a) easy determination of the permissible damage threshold, (b) rapid assessment of the fatigue limit, and (c) highlighting the dissipation and failure mechanisms of mechanical engineering materials and structures.

Thanks to thermomechanical coupling, infrared thermography and experimental analysis have made it possible to observe without contact and study the thermomechanical phenomena involved in materials and structures under various stresses. A realistic interpretation of the thermal phenomena detected leads to a wide variety of innovative applications for the mechanical performance of materials and structures,...
