Rheometrical aspects of the viscoelastic dispersion of shear waves in gel-like mechanical networks
Journal of Non-Newtonian Fluid Mechanics, 1998 A modified form of the Gross-Marvin ladder model is used to simulate gelation processes in which \(\alpha\), the viscoelastic stress relaxation exponent in the gel equation, can be varied in the range ...

Influence of mass density and mechanical properties on the surface acoustic wave velocity dispersion
Microelectronic Engineering, 2006 The surface acoustic wave technique is a non-contact, non-destructive opto-acoustic technique used to measure film thickness and material properties, such as elastic properties and density. Simulation of acoustic wave velocity dispersion revealed that the contribution density makes is larger in the first mode, whereas the modulus makes a larger ...

Dispersal Patterns, Dispersal Mechanisms, and Invasion Wave Speeds for Invasive Thistles
The American Naturalist, 2007Understanding and predicting population spread rates is an important problem in basic and applied ecology. In this article, we link estimates of invasion wave speeds to species traits and environmental conditions. We present detailed field studies of wind dispersal and compare nonparametric (i.e., data-based) and mechanistic (fluid dynamics model-based)

Characterization of Wave Dispersion in Viscoelastic Cellular Assemblies by Doublet Mechanics
Chinese Physics Letters, 2009Using the Voigt model, we analyze wave propagation in viscoelastic granular media with a monatomic lattice, planar simple cubic package and cubical—tetrahedral assembly within the context of doublet mechanics. Microstrains of elongation between the doublet particles are considered in the models.

AbstractThis paper investigates the propagation characteristics of guided waves in functionally graded annular plates considering the electro‐mechanical coupling. In the orthogonal circular curvilinear coordinate system, the elastodynamic wave equation of guided waves is derived for the functional graded piezoelectric annular plate.
