High Frequency Elastic Analysis Tool

In order to analyze, design and optimize submarine and UUV coatings, sonar decouplers and windows, the Navy requires an analytical approach which is fast, accurate, and has high physical fidelity at all frequencies of interest. Such an analytical methodology exits for wave propagation in coated, ribbed, three-dimensional elastic layered plates excited by acoustic plane waves, as described by Hull. Weidlinger Associates, Inc (WAI) proposes to develop a robust software tool which transitions this analytical solution as a documented, supported product available to a wide community of Navy users in Phase I. Parametric study support, e.g. for hundreds to thousands of cases, will be implemented. In later phases, WAI will extend the commercialization of the software to additional engineering application markets. WAI will leverage its considerable experience in underwater acoustics, strongly coupled dynamics, transducer design software, GUI development, and software development for Navy customers and applications.
