Mathematical Simulation of Magnetoelastic Deformation of Nonferromagnetic Shells in a Nonstationary Magnetic Field

Abstract

In the process of deformation of the body, the shape of its surface changes, which leads to a change in the direction of the current, that is, the electromagnetic field of the body changes, eddy currents arise, which, interacting with an external magnetic field, lead to the appearance of forces of electromagnetic origin. These forces change the stress state of the body and the electromagnetic field in it. The work mathematically simulates the magnetoelastic deformation of non-ferromagnetic thin shells under the influence of non-stationary electromagnetic forces and mechanical loads. Numerical results are obtained and an analysis is made of the electromagnetic effects of the stress-strain state of non-ferromagnetic thin shells. The effect of thickness on the stress-strain state of the shell is studied.
