在电机或磁铁线圈中，导体在其长度上承受纵向和横向应力。由于众所周知的洛伦兹力或环向应力，纵向拉伸是最常见的应力形式。垂直于磁带平面的张力，称为c轴张力，可由盆式煎饼线圈结构中的洛伦兹应力引起。虽然多丝BSCCO带对纵向拉伸的响应已知很多，但对横向应力的响应方面的工作相对较少。本文报道了多芯BSCCO-2223带和三层增强带在室温和77K下c轴拉伸强度的测量结果。
In a motor or magnet coil, the conductor experiences stresses both longitudinally and transversely to its length. Longitudinal tension is the most familiar stress configuration because of the well-known Lorentz force or hoop stress. Tension perpendicular to the flat face of a tape, termed c-axis tension, can result from Lorentz stresses in a potted pancake coil structure. While much is known about the response of multifilamentary BSCCO tapes to longitudinal tension, relatively little work has been done on the response to transverse stress. We report here measurements of the strength under c-axis tension at room temperature and 77 K of multifilamentary BSCCO-2223 tape, and a 3-ply reinforced tape.
