The problem of dynamic cavitation in nonlinear elasticity [PDF]
, 2012 The notion of singular limiting induced from continuum solutions (slic-solutions) is applied to the problem of cavitation in nonlinear elasticity, in order to re-assess an example of non-uniqueness of entropic weak solutions (with polyconvex energy)

Energy-momentum scheme for nonlinear thermo-electro-elastodynamics
, 2021 The present contribution aims at the consistent discretisation of nonlinear, coupled thermoelectro-elastodynamics. In that regard, a new one-step implicit and thermodynamically consistent energymomentum integration scheme for the simulation of thermo ...

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,
