A. M. Meirmanov, A. A. Gerus, S. A. Gritsenko BelSU, Russia
Abstract:
We consider isothermal acoustics in composite medium with two different components. Composite medium is consist from some elastic body and porous-elastic medium. Porous-elastic medium is filled with a fluid. Unique existence of the generalized solution of boundary-value problem is proved. Homogenized models are derived in various cases.
Keywords:
composite medium, periodic structure, Lame's equations, acoustics equations, porous-elastic, homogenization of periodic structures, two-scale convergence.
