Abstract :
The purpose of this paper is to present the results of stress damage observation using a new sensor and a high performance eddy current testing system. Selected digital signal processing algorithms were applied in order to enhance the obtained signals and extract parameters suitable for quantitative stress evaluation. The experimental verification of the developed technique is done and the selected results are presented
