Numerical Determination for Higher Frequencies of Simply Supported but Partially Clamped Square Plates

Abstract
Owing to the advent of high speed computers that permitted computing solutions of a large number of algebraic equations in a relatively short time, the paper utilizes the advantage of this performance to evaluate some accurate higher natural frequency parameters for vibratory simply supported square plates with partially clamped segments on the plate boundaries. Analysis is focused on two cases of the plate. The first is a simply supported plate having an equal angle-leg corner partially clamped and the second is a simply supported plate having some segments adjacent to a corner equally the lengths of partial simple support and clamped on the remainders. To carry out the frequencies accurately together with their associated modes of vibration, a dense net of representative finite element model is performed. The first twenty frequency parameters are then determined and presented in a tabular form for easy reference by other alternative methods.
