Abstract :
The strength and fracture resistance problems of Josephson junctions (JJs) defining diminution of effective superconducting area to compare with geometrical one and large parameter spreads are insufficiently studied. With account of thermal expansion anisotropy and other properties of laminated composite structures of the ceramic-ceramic and metal-ceramic types which to be proper for JJs, the set of strength and toughness parameters is computed, fracture features and toughening mechanisms are considered.
