Inclined crack through a rhombic thin superconducting strip with transport current

Abstract

The fracture properties of an inclined crack through a rhombic thin superconducting strip with transport current are investigated. The flux and current density distributions in the processes of both ascending and descending transport currents are given in clear forms. Adopting the plane strain problem model, the energy release rates (ERRs) of the inclined crack are calculated by the finite element method (FEM). The effects of inclined angle, crack length, maximal thickness and applied maximal transport current on the ERRs are discussed in detail in the process of descending transport current. All the obtained results should be of vital importance for the application of superconductors.
