Abstract

The nonlinear magnetoelastic problems for a bar-shell in a magnetic field subjected to mechanical loadings are studied. Based on the electrodynamics equations, magnetoelastic kinetic equations, geometric equations, and physical equations of a bar-shell, normal Cauchy form nonlinear differential equations, which include ten basic functions in all, are obtained by the variable replacement method. Using the difference and quasi-linearization methods, the nonlinear magnetoelastic equations are reduced to a sequence of quasilinear differential equations, which can be solved by the discrete-orthogonalization method. Numerical solutions for stresses and deformations in a bar-shell under the interaction of an electromagnetic field and a mechanical load are obtained by considering a specific example. The magnetoelastic effect on the shell by the side electric current and the magnetic induction intensity is studied. The results show that the stress-strain state in the shells can be controlled by changing the electromagnetic parameters.
