Experimental study demonstrates real-time detection of impact locations and damage in composite laminates using piezoceramic sensors, highlighting practical structural health monitoring.
Low-velocity impact is a major concern in the design of structures made of laminated composites, because it can cause extensive delaminations inside that can severely degrade the load-carrying capability. To develop the impact techniques providing on-line diagnostics of smart composite structures can be in the health monitoring of structures susceptible to impacts. In this paper, we discuss signal processing techniques for the simultaneous monitoring of impact locations and using piezoceramic sensors (PZT).
