A three dimensional wax analogue for the calibration of the electrical potential technique of crack growth monitoring

ABSTRACT Three dimensional wax models have been used to obtain calibrations for the DC potential drop measurement method. By taking potential readings at both sides of the specimen, quarter thumbnail cracks can be identified.
