Damage Evaluation Based on Electrical Resistance Measurement

Abstract:

Article Preview

The formulae between electrical resistance change and damage in metals were studied on the basis of different damage mechanisms. This DC electrical resistance is a more sensitive parameter to the initiation of microcracks during the irreversible damage accumulation process. Measurement of low electrical resistance due to accumulative damage is discussed. Agreement between evaluations of ductile damage via electrical resistance change and elasticity modulus measurement is good.
