Abstract
The Power Flow Finite Element Method (PFFEM) is a relatively new method for analyzing complicated structures such as ships at high frequencies where the standard finite element method is not practical. Power Flow Finite Element Analysis (PFFEA) also has advantages with respect to Statistical Energy Analysis (SEA), the high frequency analysis method is current use. This report deals with investigations conducted to extend the development of the PFFEM beyond its current infancy and begin implementation of this method into the VAST suite of computer codes. Through this work, the PFFEM theory has been developed (but not implemented, as yet) for thin plates of arbitrary shapes. As well, junctions in beam networks were studied extensively while studies of oblique incidence junctions and junctions at beam/plate interfaces were commenced. TRUNCATED
