Structure-Borne Traveling Waves (SBTWs) have significant promise as a means of underwater propulsion, drag reduction, and solid-state motion. However, there is poor understanding of how to tailor SBTWs favorable for these applications. This study est

As the complexity and scales of dynamic models increase, novel and efficient model correlation methodologies are vital to the development of accurate models. Classically, to correlate a Finite Element Model (FEM) such that it matches a dynamic test,
