英文摘要：

In this paper, the nonlinear magneto-elastic kinetic equations, the geometric equations, the physical equations and the electrodynamics equations of thin current-carrying strip-plate under the action of the coupled field are given, and the normal Cauchy form nonlinear differential equations, which includes ten basic unknown functions in all, were obtained by means of variable replacement method. Using the difference method and quasi-linearization method, the nonlinear magneto-elastic equations were reduced to a sequence of quasi-linear differential equations, which can be solved by the method of discrete orthogonalization, Through specific example, the numerical solutions of the stresses and deformations in the thin current-carrying strip-plate mixed with fixed and simply supported edges were obtained. The results that the stresses and deformations of the thin current-carrying strip-plate mixed with fixed and simply supported edges are altered with the variation of the electromagnetic parameters were discussed. Through a special case, it is shown that the deformations of the strip-plate can be controlled by changing the electromagnetic parameters.
