This paper describes results to the research obtained in a joint project in the BRITE-programme of the European Community (1). One specific part of the project has the objective to investigate the potential of micromagnetic NDT-techniques, developed elsewhere for stress analysis (2), for the insitu-measurement of prestressing cable-forces.
