Abstract


The use of Guided Waves (GW) is a potentially attractive solution to inspect large composite structures from a limited number of transducers thanks to the capability of these waves to propagate over large distances. However, the multimodal and dispersive nature of GW, combined with the anisotropic nature of composite materials makes it difficult to analyze and interpret the signals. Predicting the response of a guided wave SHM system in industrial configuration with complex geometries is therefore very difficult, which is a serious impediment for the development of such technology. We present here, illustrated with examples, the current capabilities of the guided wave module of the simulation software CIVA 11and the developments in progress at CEA that will be integrated into future versions of CIVA GW for SHM of composite structures.
