The authors have developed a method of real time stress measurement by a scanning infrared camera. It has been shown that the cyclic plastic zone at the tip of a fatigue crack can be monitored. Further, the HRR singurality of 1/γ in the distribution of plastic strain energy in the cyclic plastic zone, where γ is the distance from the crack tip, has been verified experimentally. It has been shown that the fracture mechanics parameters such as stress intensity factor, K, and J-integral can be measured by the developed system.
