Using the Partial Wave Method for Wave Structure Calculation and the Conceptual Interpretation of Elastodynamic Guided Waves

open access: yesApplied Sciences, 2018
The partial-wave method takes advantage of the Christoffel equation’s generality to represent waves within a waveguide. More specifically, the partial-wave method is well known for its usefulness when calculating dispersion curves for multilayered ...

Generalized elastodynamic model for nanophotonics [PDF]

open access: yesPhysical Review B, 2020
A self-consistent theory for the classical description of the interaction of light and matter at the nano-scale is presented, which takes into account spatial dispersion. Up to now, the Maxwell equations in nanostructured materials with spatial dispersion have been solved by the introduction of the so-called Additional Boundary Conditions.

Revisiting stress propagation in a three-dimensional elastic sphere under diametric loading

open access: yesNihon Kikai Gakkai ronbunshu
The stress propagation for a three-dimensional elastic sphere under a diametric loading condition in the framework of the linear elastodynamics is revisited. By describing displacements in terms of scalar and vector potentials using the Helmholtz theorem,

Non-Hermitian elastodynamics in gyro-odd continuum media

open access: yesCommunications Materials, 2022
Active metamaterials can host non-Hermitian interactions that defy the conservation laws of linear elasticity, leading to unusual phenomena such as one-way energy transmission and odd-elastic moduli. Here, robust unidirectional Rayleigh surface waves are

Elasto-Dynamics of Quasicrystals

open access: yesCrystals, 2016
A review on elasto-dynamics of quasicrystals (QCs) and their applications based on mathematical elasticity is given. In this study, recent studies on elasto-dynamics of QCs are reviewed, in which the focus of the problem lies in the role of phason ...

Functional Parametric Elasto-Dynamics for Efficient Multicomponent Design

open access: yesComputation, 2022
In industrial settings, engineering products are often divided into separate components for detailed conception. They often require iterative corrections between different designers/teams to optimize the final product with all components assembled into a

Connecting Atomistic and Continuous Models of Elastodynamics

open access: yes, 2016
We prove long-time existence of solutions for the equations of atomistic elastodynamics on a bounded domain with time-dependent boundary values as well as their convergence to a solution of continuum nonlinear elastodynamics as the interatomic distances ...

Formation of finite-time singularities for nonlinear elastodynamics with small initial disturbances

open access: yes, 2019
This article concerns the formation of finite-time singularities in solutions to quasilinear hyperbolic systems with small initial data. By constructing a special test function, we first present a simpler proof of the main result in Sideris' "Formation ...

Generalized dynamics of moving dislocations in quasicrystals

open access: yes, 2010
A theoretical framework for dislocation dynamics in quasicrystals is provided according to the continuum theory of dislocations. Firstly, we present the fundamental theory for moving dislocations in quasicrystals giving the dislocation density tensors ...
