Effect of Ferromagnetic Particles on the Effective Mechanical Properties of Bulk Superconductor with Interfacial Effect

Abstract

This study focused on investigating the effects of various factors on the mechanical properties of superconducting matrix composites reinforced with ferromagnetic particles and interface phases when exposed to external magnetic fields. A micromechanical model was created by simplifying the basic properties and composition of the interface, utilizing principles such as Eshelby’s equivalent inclusion theory and Hooke’s law, as well as applying uniform stress boundary conditions. Through the development of equations, the study predicted changes in effective mechanical properties, highlighting the significant influence of parameters like the interface phase, inclusions, and magnetic field on the effective elastic modulus and magnetostriction of the composite material. By shedding light on these relationships, the research offers valuable insights for the manufacture and application of ferromagnetic particle-reinforced superconducting matrix composites with interface phases, providing a foundation for future research in this area.
