Acoustic waves in real life

[Tuman_1232]

Hello everyone,
I have a project where I need to predict acoustic wave propagation in elastic body.
Do you know some sort of theory and solved theoretical problem that I can start with in this topic?
Thank in advance

did you try googling "acoustic wave propagation in elastic body" ?

This sounds like the type of problem we studied in my Advanced Vibrations course.
I recall deriving the formula to predict the 3D response at any location on an infinite shell of known material properties to an impingement excitation.
When I asked the professor "what is this used for?" he replied that it was to predict how a submarine hull responds to sonar signals hitting it. Probably a useful and lucrative Academic research topic during the Reagan defense build-up era.

I recall the standard analysis setup was a triple partial differential equation (in spatial coordinate systems of X, Y, Z). The formula was summarized by the DEL operator ∇. A long complicated formula of which most terms were luckily deleted or ignored as insignificant contributors.

And that's about all I can recall since it has been purged from my gray-haired memory.

not many infinitely long submarines out there …

doing school work (even post-grad) in '84 … pup!
