Abstract
Residual stress in a YBCO/Ag composite was estimated by studying the differ ence between the thermal expansion coefficients of the silver particles and the brittle Y1Ba2Cu3Ox (Y123) superconducting matrix using the finite elem ent method. The influence of this residual stress on crack propagation arou nd the silver particles dispersed in the Y123 matrix is discussed.
