MEASUREMENT OF SUB-CRITICAL FLAW GROWTH IN STRESS CORROSION, CYCLIC LOADING AND HIGH TEMPERATURE CREEP BY THE DC ELECTRICAL RESISTANCE TECHNIQUE

The DC electrical resistance technique has been applied to the measurement of subcritical flaw growth in fracture toughness specimens of different geometries under conditions of stress corrosion, cyclic loading and high temperature creep. The technique has been developed to give a linear potential change as a function of crack length, combined with maximum sensitivity. Comparisons made between this technique and the ultrasonic technique have enabled several sources of error to be identified and corrections to be made for these.
