Theory and computation of higher gradient elasticity theories based on action principles [PDF]
, 2017 In continuum mechanics, there exists a unique theory for elasticity, which includes the first gradient of displacement. The corresponding generalization of elasticity is referred to as strain gradient elasticity or higher gradient theories, where the ...

Fractonic line excitations: An inroad from three-dimensional elasticity theory [PDF]
Physical review B, 2018 We demonstrate the existence of a fundamentally new type of excitation, fractonic lines, which are line-like excitations with the restricted mobility properties of fractons. These excitations, described using an amalgamation of higher-form gauge theories

The fundamentals of non-singular dislocations in the theory of gradient elasticity: dislocation loops and straight dislocations [PDF]
, 2012 The fundamental problem of non-singular dislocations in the framework of the theory of gradient elasticity is presented in this work. Gradient elasticity of Helmholtz type and bi-Helmholtz type are used.

Numerical study of the Sturm–Liouville problem [PDF]
Iranian Journal of Numerical Analysis and OptimizationThe article discusses the general Sturm–Liouville problem. To solve it numerically, a new algorithm is proposed, which is based on the varia-tional principle and does not use saturation.

An effective field theory of magneto-elasticity
SciPost Physics, 2022 We utilize the coset construction to derive the effective field theory of magnon-phonon interactions in (anti)-ferromagnetic and ferrimagnetic insulating materials.

Ab initio calculations of third-order elastic coefficients [PDF]
Phys.Rev.B 106 (2022) 214104, 2022 Third-order elasticity (TOE) theory is predictive of strain-induced changes in second-order elastic coefficients (SOECs) and can model elastic wave propagation in stressed media. Although third-order elastic tensors have been determined based on first principles in previous studies, their current definition is based on an expansion of thermodynamic ...

New directions and perspectives in elastic instability and turbulence in various viscoelastic flow geometries without inertia [PDF]
Low Temperature Physics 48, 6, 552-568 (2022), Special issue of
LTP (Low Temperature Physics) Azbel-90, 2022 I shortly describe the main results on elastically driven instabilities and elastic turbulence in viscoelastic inertia-less flows with curved streamlines. Then I describe a theory of elastic turbulence and prediction of elastic waves at Re<<1 and Wi>>1, which speed depends on the elastic stress similarly to the Alfven waves in magneto-hydrodynamics and
