Force and moment admittance of plates under arbitrary fluid loading
Abstract
Exact closed form expressions are given for the line force and moment admittances of an infinite thin elastic plate immersed in compressible fluid. Very simple approximations to the admittances are found in the heavy fluid loading limit. The approximations are shown to completely cover the low-frequency range which has previously not been dealt with, even by the numerical computations of Nayak [1]. The plate response throughout the near-field of the line of excitation is also obtained in simple form.
