Fatigue Damage Sensing in Smart Carbon Fiber Concrete by Electrical Resistivity Measurement

Abstract:

The possibility of sensing the damage in smart carbon fiber concrete (SCFC) during the fatigue loading process by electrical resistance measurement is investigated in this paper. The damages occurred and accumulated in the carbon fiber concrete specimens under the fatigue loading destroy the local conductive network in the areas near the micro-cracks and cause the whole volume electrical resisitivity increasing. It is verified that the resistance measurement has a great potential to monitor and evaluate the damages in carbon fiber concrete during the whole fatigue process on line.
