摘要：
To evaluate fatigue state of austenitic and ferromagnetic steels a sensors array was developed. The studied sample had different degree of fatigue damage until the state of fatigue cracks. The resolution of sensors array was improved using maximum likelihood procedure. To determine the weight vector, the forward problem was solved, using dyadic Green's functions for layered media.
