Hencky–Bolle’s plates of medium thickness on elastic subsoil [PDF]
Acta Scientiarum Polonorum. Architectura, 2020 The paper presents equations of theory of plates resting on elastic subsoil. Theories of thin and medium thickness plates applied to subsoils with one and two parameters, including Vlasov’s and Winkler’s subsoils, were analysed.

Effective medium theory for elastic metamaterials in thin elastic plates [PDF]
Physical Review B, 2014 An effective medium theory for resonant and non-resonant metamaterials for flexural waves in thin plates is presented. The theory provides closed-form expressions for the effective parameters of arrangement of inclusions or resonators in thin plates as a function of the filling fraction of the inclusions, their physical properties and the frequency. It

AHARONOV–BOHM EFFECT AND DISCLINATIONS IN AN ELASTIC MEDIUM [PDF]
Modern Physics Letters A, 2006 In this work we investigate quasiparticles in the background of defects in solids using the geometric theory of defects. We use the parallel transport matrix to study the Aharonov–Bohm effect in this background. For quasiparticles moving in this effective medium we demonstrate an effect similar to the gravitational Aharonov–Bohm effect. We analyze this

Сomputation of prismatic shells in elastic medium
Инженерно-строительный журнал, 2015 The paper presents a computation procedure of physically nonlinear prismatic shells with the sealed ends. It is known that plates reinforced by stiffening ribs and located in the elastic medium can be calculated in a similar way as uniform ones (without ...

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1983 Discussions are made on the possibility of expressing elastic deformation of an inhomogeneous material by dislocations distributed in a homogeneous elastic medium. A model of the inhomogeneous material is employed, which is composed of plane rectangular regions with different elastic constants.

On Dynamic Stability of a Nonlinear Aeroelastic System
Известия Иркутского государственного университета: Серия "Математика", 2018 A nonlinear mathematical model of a device related to vibratory technology is considered. The device is intended for the intensification of technological processes, for example, the mixing process. The action of such devices is based on the vibrations of
