We have studied the mechanical properties of melt-processed single-grain Sm-Ba-Cu-O bulks with and without silver doping. The tensile strength of the silver-doped sample was 37.4MPa and about 1.5 times larger than that of the undoped sample. Dimension effects can be estimated from the Weibull distribution function and the effective volume of the samples. It was shown that the strengths, which were obtained in the samples with different dimensions or with different measurement methods like bending strength, can be converted into relative strengths by considering this effect. The bending strength of the silver-doped sample was estimated to be 70-120MPa.
