The effect of nature of porous material on diffuse field acoustic transmission of the sandwich aerospace composite doubly curved shell

This paper reviews the most of previous works through vibroacoustic performance of shell structures in past years (1957–2019). The major end is especially placed to collate the researches carried out in the area of power transmission through shell structures during the last 60 years. For this purpose, a series of categories are first highlighted in order to classify the issues that should be searched. The review is then directed with emphasis on the kinds of shells with different geometries containing cylindrical and doubly curved shells. Later on, not only a popular discussion is proposed to model the acoustic behavior of shells based on the different theories (classical, shear deformation and three-dimensional) but also a perfect explanation is provided wherein the importance of modeling the structures according to the different materials is revealed. To extend the review, various boundary conditions (finite and infinite) are also investigated. Besides, the further effects of external environments as fluid and thermal are inspected. Since the type of incident field can be impressive on the sound insulation specification of these shells, the structure is characterized based on the various acoustic excitations involving plane wave and point source incidences. Furthermore, some descriptions on the solution procedures (analytical, experimental and numerical) are also given. As a result, the review is centralized through other matters such as control and optimization techniques in order to improve the vibroacoustic behavior of shell structures.
