Magneto-Elastic Analysis of a Superconducting Film with a Crack-Like Flaw

Abstract

This paper analyzes the magnetoelastic response of type-II superconducting film. Cracks can lead to large local current enhancement near the crack-like flaw tips, Based on the previous work, the effects of the flaw on the stress field are discussed. It is found that the presence of the flaw markedly enhances the concentration of the stress near the tips of the flaw. In addition, as the geometry increases, the position where the maximum stress occurs increases.
