Analysis of the Fracture Mechanics Behaviour of an Additive Manufactured Titanium Alloy Via a Thermography-Based Technique

The fatigue crack propagation behaviour of material fabricated by the SLM process is investigated by using several complementary experimental techniques aiming at addressing the problems of early identification of crack initiation and growth, the transition between the fatigue crack growth regimes, and the assessment of parameters capable of describing the plastic work at the crack tip. We provide a report on the preliminary study based on the thermographic data reflecting the fracture mechanics behaviour of a titanium-based additive manufactured material.
