Mathematical simulation of magnetoelastic deformation of electrically conductive plate in a magnetic field

The effect of the coupling of dynamic and mechanical displacements of electrically conductive bodies with an electromagnetic field is due to ponderomotive Lorentz forces. Significant effects of ponderomotive interaction occur under high-frequency vibrations at large displacement amplitudes, pulsed magnetic fields, and current-carrying elements. The construction of optimal designs of modern technology operating in magnetic fields is associated with the widespread use of structural elements. On-chip integration of elements in electronics, mechanics, computer science and measuring technology led to the unification of these technologies, the creation of microsystem technology, and the emergence of microelectromechanical systems. Microsystem engineering and nanotechnology are closely related to each other: on the one hand, microelectromechanical systems – actuators - are used as microtools for manipulating and studying nanoobjects, micro- and nanorobots. An electrically conductive flexible plate is mathematically simulated under the influence of a time-varying mechanical force and a time-varying external electric current, taking into account the anisotropy of conductive properties. Numerical results are obtained and an analysis of the electromagnetic effects of the stress-strain state of an electrically conductive plate is performed. The effect of an external electric current on the stress state of a flexible annular plate is studied considering the anisotropy of conductive properties.
