Notes:
Bi-2223 tapes are usually subjected to tensile strain, bending strain and compressive stressin the process of fabrication and applications. In this study, we have measured the critical current ofBi-2223 tapes as a function of transverse compressive stress. The effects of the cross section size andprocessing defects on the stress characteristics of AgMn-alloy sheathed Bi-2223 tapes are compared.The experimental results showed that the onset transverse compressive stress for degradation of Ic waslower in the thinner tape with a thin Ag sheath due to the stress concentration on the irregularinterface. The bubbled tapes were more sensitive to the transverse stress compared to the nonbubbledtapes
