Résumé

The local strain response of a composite plate is monitored with embedded fibre Bragg gratings during low velocity impacts. The modal characteristics of the plate, i.e. its eigenfrequencies, coarse mode shapes and modal damping ratios are obtained from the transient response to an impact and are used for damage evaluation after impact.
