Abstract
This approach proposes a strategy based on modeling poroelastic doubly curved composite shells on a Pasternak-type Elastic Foundation (PEF). Likewise, a general formulation is developed considering Hamilton's principle to extract dynamic equations based on the shear deformation shallow shell theory (SDSST). Biot's study is also used to analyze wave propagation through a porous core. According to a finite vibroacoustic problem, it is essential to either excite the construction via an acoustic source or consider enough modes. Therefore, in addition to the formulation of the acoustic pressures based on the modal infinite double Fourier series, some factors are extended as a series harmonic solution. Before verification of the outcomes, some configurations with their convergence algorithm versus dimension and frequency are plotted. The results represent the effect of modeling poroelastic doubly curved composite shells subjected to a PEF on acoustic characteristics regarding each of Winkler spring and shear layer stiffness. Additionally, the transverse vibration of the construction is explored for the angle of incidence.
