Nonlocal elastodynamics and fracture [PDF]
Nonlinear Differential Equations and Applications NoDEA, 2021 AbstractA nonlocal field theory of peridynamic type is applied to model the brittle fracture problem. The elastic fields obtained from the nonlocal model are shown to converge in the limit of vanishing non-locality to solutions of classic plane elastodynamics associated with a running crack.

Scattering fidelity in elastodynamics [PDF]
Physical Review E, 2006 The recent introduction of the concept of scattering fidelity, causes us to revisit the experiment by Lobkis and Weaver [Phys. Rev. Lett. 90, 254302 (2003)]. There, the ``distortion'' of the coda of an acoustic signal is measured under temperature changes. This quantity is in fact the negative logarithm of scattering fidelity.

Observation of Brillouin scattering in a high-index doped silica chip waveguide
Results in Physics, 2023 We report the observation of Brillouin backscattering in a 50-cm long spiral high-index doped silica chip waveguide and measured a Brillouin frequency shift of 16 GHz which is in very good agreement with theoretical predictions and numerical simulations ...

Non-Hermitian elastodynamics in gyro-odd continuum media
Communications 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

Revisiting stress propagation in a three-dimensional elastic sphere under diametric loading
Nihon Kikai Gakkai ronbunshuThe 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,
