A RECIPROCITY RELATION FOR FLUID-LOADED ELASTIC PLATES THAT CONTAIN RIGID DEFECTS

A reciprocity relation between the farfield behaviour of the scattered fields generated by incident waves, either flexural plate waves, or incident from the fluid, upon rigid defects embedded in a thin elastic, fluid-loaded, plate is derived. This reciprocity result is then illustrated upon model problems for which the explicit solution can be determined and the relation demonstrated.
