Abstract:

The general objective of the present work was to look for alternatives to the conventional time domain model for the oscillatory forces on plates, using what data could be found in the literature. To the extent which information could be extracted from existing sources, an alternate to the conventional model can be synthesized, but only for sinusoidal plate or fluid motion. The results do not obviously point the way toward a real-time non-linear model suitable for more complex forms of motion. an approach for which there had been high initial hopes the functional polynominal appeared, at the end of the work, not to be so promising.
