摘要

The paper deals with an analytical model of stresses acting in the superconductor YBCO during an oxygenation process to transform the tetragonal lattice of the non-superconductive phase ${hbox{YBa}_2hbox{Cu}_3hbox{O}_{7-{x_0}} (x_{0}=0.9)}$ to the orthorhombic lattice of the superconductive phase ${hbox{YBa}_2hbox{Cu}_3hbox{O}_7}.$ Accordingly, the oxygenation-induced stresses originate as a consequence of the difference in dimensions of the crystalline lattices. Additionally, critical temperature of the oxygenation process with regard to a crack formation in the superconductor YBCO is derived.
