N2 - Structural traveling waves have significant potential in applications such as propulsion and drag reduction. Using the two-mode excitation method, traveling waves which are both steady-state and open-loop controlled can be generated on various structures such as beams, plates, and cylinders. In order to develop this method further for applications such as drag reduction, more representative cases must be investigated. This work models and experimentally validates traveling waves generated on a thin, fully clamped plate with flush-mounted piezoelectric actuators. A two-step experimental modal analysis is conducted on a free and then clamped plated to validate and update a finite-element model of the plate. The finite element model, which has been developed in-house, accounts for piezoelectric actuators, pre-stresses in the plate, and non-ideal (elastic) clamped boundary conditions. The validated model is then used to compare experimental- and model-generated traveling waves.
