The superconducting magnets which are composed of superconductors have superior properties which normal magnets do not possess. With the development of the superconductors which can be used in large-scale applications,the superconducting magnets have been applied in many applications. As the superconductivity keeps developing,the mechanical behaviour also attracts attention of the researchers. Superconductors have complex nonlinear electromechanical behavior. The investigations of improving mechanical and magneto-thermal stability of superconductors and realizing the tunability of electromagnetic behavior with mechanical loadings have important scientific significance and application value. This proposed project will study the following problems: (1) The effects of inclusions on the mechanical and electromagnetic behavior will be analyzed so that the optimized distribution of inclusions which enhances the mechanical stability and improves the trapped field can be obtained; (2) We aim to investigate the flux jump in the superconductors by considering the electromechanical coupling behavior, analyze the impact of mechanical loadings on the magneto-thermal stability and the approach to improve the magneto-thermal stability; (3) The theoretical model which can describe interaction between the superconductor and ferromagnet will be established, the relationship between the mechanical loadings and electromagnetic behavior in Superconductor-Ferromagnet structure is studied and the tunability of electromagnetic behavior with mechanical loadings is realized;(4) The structure which can achieve magnetic cloaking will be designed by means of theoretical calculations and experiments, and the effects of deformation on the invisibility of cloaking structure in non-uniform field and time varying field are discussed.
