| description | In this paper, the flux-pinning-induced elastic stress analysis considering the crack-inclusion interaction is carried out for a bulk superconductor in the magnetization process. A approximate model for the crack problem of a bulk superconductor with nonsuperconducting inclusions (particles) dispersed in a superconducting matrix is described. The crack is simulated as a continuous distribution of edge dislocations in the solution procedure. The obtained results show that, the shear modulus, inclusion-crack size, inclusion-crack distance, and also the magnetic field have obvious effects on the stress intensity factors (SIFs) at the crack tips of the superconductor. |
