Abstract
Bi2Sr2Ca1Cu2O8+x (Bi-2212) wire is the potential material for the design of the high field superconducting magnet. However, compared with excellent current-carrying capacity, low mechanical strength can restrict the wide application of Bi-2212 wire. The superconducting filaments of Bi-2212 wire is sensitive to strain and is prone to fracture, which can lead to the degradation of critical current. Therefore, it is necessary to study the damage behavior of Bi-2212 round wire under external loads. In this paper, the three-dimensional mechanical damage and degradation of critical current in Bi-2212 composite wire under axial tensile load, radial compression load, bending and torsional loads are systematically investigated using ordinary state-based elastoplastic peridynamic (PD). The axial tensile simulations with the process of damage and thermal residual stress are in agreement with the experiment, and the critical current degradation with tensile strain is qualitatively predicted. The effect of plastic deformation of alloy on damage of filament bundles under radial compression load is explored. Finally, the simulations also reveal the damage characteristics of filament bundles in Bi-2212 round wire under torsional and bending loads. The above results are expected to provide a reference for application of Bi-2212 HTS round wire.
摘要
Bi2Sr2Ca1Cu2O8+x (Bi-2212)圆线是高场超导磁体研制中极具潜力的材料. 然而, 与优良的载流能力相比, 其较低的力学**度限制 了Bi-2212圆线的广泛应用. Bi-2212圆线的超导芯丝对应变敏感且容易断裂, 进而导致临界电流发生退化, 因此对Bi-2212圆线在外载荷 作用下的损伤行为进行研究是十分必要的. 本文采用常规态型弹塑性**场动力学(PD)方法, 系统研究了Bi-2212复合线材在轴向拉伸载 荷、径向压缩载荷、弯曲载荷和扭转载荷作用下的力学破坏行为和临界电流退化. 在轴向拉伸的计算中考虑了损伤扩展和热残余应 力, 数值结果与实验结果吻合较好, 并且定性预测了临界电流随拉伸应变的退化, 给出了径向压缩载荷下合金的塑性变形对芯丝束破 坏的影响规律. 最后, 数值模拟结果揭示了Bi-2212圆线在扭转和弯曲载荷作用下的芯丝束的破坏特征, 本文的结果可为Bi-2212高温超 导圆线的应用提供理论基础.
