Abstract

The susceptibility of composite to withstand impact damage challenge the existing maintenance technologies related to damage detection. The problem of impact localisation in composite structures requires a reliable technique for impact damage detection. This paper investigates the reliability of strain data for impact damage localisation. A finite element model has been developed to simulate the impact strain wave propagation which can be used to ease the signal processing data. A series of impacts is experimentally performed on a smart composite panel instrumented with low-profile, embedded piezoceramic transducers. Two wave velocity propagation characteristics are developed using the strain data from both the simulation and experimental works. A Genetic Algorithm, together with the modified triangulation/ multilateration procedure utilises the strain wave velocities propagation for impact positioning. The result shows that the finite element model can assist the experimental work for impact localisation in composite panel with less than 2 percent of total error per area.
