Abstract :
The purpose of this paper is to present the results of stress damage observation using a giant magnetoresistive sensor and a high performance measuring 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.
