Effect of corrosive sea water on the stress state and endurance of elements of thin-walled structures

Acoustic radiation from a submerged hollow FGM sphere

“…The proposed model is of basic academic interest due to its inherent value as a canonical problem in structural acoustics. It is of practical value for structural acoustic engineers involved in the dynamic analysis and design of submerged thick-walled inhomogeneous spherical vessels, storage tanks, and underwater sonar transducers [24][25][26][27][28]. The presented exact solution can provide proper physical insight in situations, where due to the complexity of the internal coupling of the wave fields, the thin-shell theory is inadequate and the full theory of elasticity becomes necessary for studying elastoacoustic interactions.…”
