Mk. Rahman et A. Ertas, ACOUSTIC POWER RADIATION FROM A RECTANGULAR PLATE WITH MIXED BOUNDARY-CONDITIONS, Thin-walled structures, 18(1), 1994, pp. 3-22
The total average acoustic power radiation from one side of a baffled
rectangular flat plate, vibrating in its natural modes under two oppos
ing ends fixed and the other two ends simply supported boundary condit
ions, has been investigated. Numerical results on the acoustic power r
adiation by the plate have been obtained for various mode orders, aspe
ct ratios, and thickness ratios. Expressions for the acoustic power ra
diation by plates under specific edge restraints have been derived in
terms of the far-field acoustic pressure distribution.
