摘要：
In this paper, the critical current density degeneration of polycrystalline superconductors with applied stress or strain is investigated from the point of view of extends Ginzburg-Landau theory. The mechanism of the current density degeneration is assumed that the properties of Josephson junctions of the grain boundary are affected by the stress or strain. Based on the extended GL theory and the linear elastic theory, also with the uniform strain assumption, we numerically solve the weakly coupled GL equations in which the deformation of the grain boundary of superconductors is considered via the strains.
