Abstract
Copper-laminated REBCO tape is one of the best choices for manufacturing high-current-carrying cables in fusion projects and particle accelerator designs due to their excellent current-carrying performance in high magnetic fields. In order to maximize the electromechanical properties of the cable after winding, the bending properties of three kinds of copper-laminated REBCO tapes are analyzed. The experimental results show that the bending properties of the three REBCO tapes are different from each other. A three-dimensional finite element simulation model is also established to study the strain field of the superconducting layer under different bending radius and bending states (REBCO layer is inside/outside of bending). The simulation results are in good agreement with the calculated formula, which verifies the correctness of the finite element model. The edge effect is found by the simulation results of strain distribution along tape width. The influence on strain field distribution by changing the tape width and the thickness of the copper-laminated layer is investigated under two bending states. Finally, the critical strain values of each tape under two bending states are obtained by combining the results of experiments and the finite element model. In addition, the finite element model can study the stress and strain field distribution of each functional layer of REBCO tape along axis a, b and c.
