What is a longitudinal wave? Learn the definition and various parts of a longitudinal wave. Understand the amplitude and wavelength of a...
Plane longitudinal waves propagating in a Slepyan-Palmov medium that consist of a carrier medium and an ensemble of nonlinear oscillators are considered. The system of equations of dynamics is reduced to one equation for the longitudinal displacement of the carrier medium. The propagation of harmonic...
6.2.2 Longitudinal visco-elastic waves propagating in Maxwell bars The longitudinal waves in Maxwell bars can be discussed in a similar way, for which the governing equations consist of Eqs. (2.12), (3.13), and (6.4), namely: (6.26) ∂v∂X=∂ɛ∂tρ0∂vdt=∂σ∂X...
In this paper, we study long nonlinear waves of small-amplitude propagating along an elastic rod when there is a strong interaction between longitudinal and torsional movements (longitudinal–torsional waves). The system of nonlinear hyperbolic equations describing such waves was obtained in [14]. ...
Cortical bone is composed of osteons, which are cylindrically shaped structures composed of multiple types of cells and bone matrix proteins, and are directed parallel to the longitudinal axis of bone. From: Materials Today, 2018 About this pageSet alert ...
ONE - DIMENSIONAL NONLINEAR INDUCED DYNAMICS OF ACOUSTIC WAVES IN FINITE DOMAIN In the present work the problem of the one dimensional time dependent viscous compressible gas flow excited by a small external time dependent spaceand time periodic force is considered within the framework of the Navier...

The metamaterial’s unit cell consists of a diamond-shaped frame and a pair of orthogonal springs, displaying quasi-zero stiffness through the interaction of lateral and longitudinal springs, which balances internal pressure and tension. The transmission and dispersion of longitudinal waves in these ...
Just as cross-sectional data can be informative in some situations, two waves of data can be beneficial in contexts such as when an exposure is involved (e.g., pre/post tests), or if the central goal is prediction (e.g., trying to predict scores on Variable A at time T as a ...
