The ultrasonic techniques of flaws detection and evaluation usually rely on linear models. High mechanical stress generates non-linear phenomena. Models suited to fit the input-output characteristics and the existence of non-linear behaviors, if any, allow improved sensitivity and early detection of the onset of cracks. We propose a technique of nonlinear characterization of the response, adequate for a real time industrial implementation.
