Abstract

This contribution is focused on investigations concerning the damage diagnostics of surface structures using Lamb waves. Based on finite element calculations the potential feasibility for the detection of delaminations, inclusions or cracks have been investigated. For the actuator and sensor material a thin PVDF foil has been used, which is applied to the corresponding component. The advantage of these foils over piezoceramics is that they are also applicable to arbitrarily curved surfaces and their stiffness is compatible with polymer laminates. By evaluating the signals of well-defined arrangements of the electrodes and the generated Lamb waves, existing defects can be identidied. Their exact localization becomes possible with the help of runtime calculations.
