EFFECTS OF AXIAL TENSILE AND BENDING STRAINS ON CRITICAL CURRENTS OF MONOCORED AND MULTICORED (BI,PB)(2)SR2CA2CU3O10-AG TAPES

Improved strain sensitivity of critical currents I-c of the multicored over the monocored (Bi,Pb)(2)Sr2Ca2Cu3O10-Ag tapes is shown for bending strains, but not for axial tensile strains. The improved mechanical tolerance is due, in part, to a better alignment of the Bi-cuprate platelets achieved in the multicored tapes. Furthermore, the difference in the response to these tapes to axial tensile and bending strains is due to the difference in the precise manner in which the strains are applied to the tapes.
