Flow through an Electromechanical Tube Driven by a Voltage
Yilin Qu, Hendrik J. Viljoen, Jiashi Yang
We study the axial flow of a nonviscous and incompressible fluid in a circular tube made from an electromechanical material. The tube is driven into radial motion by an electric vo…
A Continuum Theory of Elastic-Ferromagnetic Conductors
Jiashi Yang
In this paper, a phenomenological theory of saturated ferromagnetoelastic conductors is established using a multi-continuum model and the classical laws of mechanics, thermodynamic…
A Macroscopic Theory of Saturated Ferromagnetic Conductors
Jiashi Yang
A phenomenological theory of rigid and saturated ferromagnetic conductors is constructed from a four-continuum model consisting of a rigid lattice continuum, a bound charge continu…
Theoretical Analysis of Quartz Plate Acoustic Wave Resonators and Sensors Using Three-Dimensional Equations of Anisotropic Elasticity or Piezoelectricity
Jiashi Yang
This is a review of theoretical results from the three-dimensional equations of anisotropic elasticity or linear piezoelectricity on waves and vibrations in quartz crystal plates.…
An Alternative Derivation of the Landau-Lifshitz-Gilbert Equation for Saturated Ferromagnets
Jiashi Yang
The Landau-Lifshitz-Gilbert equation for rigid and saturated ferromagnets is derived using a two-continuum model constructed by H.F. Tiersten for elastic and saturated ferromagnets…
Frequency perturbation integral for piezoelectric quartz crystal microbalances based on scalar differential equations
Jiashi Yang
We study frequency shifts in a piezoelectric quartz resonator induced by a surface mass layer for sensor applications. The scalar differential equations for thickness-shear modes i…
