The use of piezoelectric coupling in structural monitoring as a feature robust to EOV

Description

This paper introduces a new method for utilizing piezoelectric elements placed within a structure or system for structural health monitoring purposes. The novel damage feature suggested here is the piezoelectric coupling factor. It is proven to be sensitive to damage presence and its severity and it is not significantly affected by changes in environmental and operating conditions. The effectiveness of this new damage feature is evaluated through simulations and experiments.
