Abstract : An experimental calibration was obtained for the potential difference across a crack in high strength sheet steels. Two theoretical calibrations were worked out. In contrast with the corresponding elasticity problem, a solution which approximates the slot and crack as an ellipse of constant semi-minor axis yields the best agreement with experiment. (Author)
