WebConsider a time-harmonic acoustic wave incident onto a doubly periodic (biperiodic) interface from a homogeneous compressible inviscid fluid. The region below the interface is supposed to be an isotropic linearly elastic solid. This paper is concerned with the inverse fluid-solid interaction (FSI) problem of recovering the unbounded periodic interface … http://sokocalo.engr.ucdavis.edu/~jeremic/PAPERSlocalREPO/CM2491.pdf
WebJun 19, 2024 · In common usage the term “acoustics” seems to refer to all types of mechanical waves in solids, liquids, and gases, and that is the sense in which the term is used in the present work. The treatment of acoustic waves in solids falls naturally into two regimes, depending on wavelength. If the wavelength is much greater than the interatomic … WebAs explained in the previous Section, different types of elastic waves can be studied, i.e., volume (P waves) and surface waves (S and R waves). The P waves are analyzed by means of the so-called direct test, with the hammer hitting on the surface of the solid and one accelerometer receiving the wave, as material vibration, measured on a point of the …
