“…The distribution shows that the compressive strain is the minimum at the edges as compared to the central region. The strain distribution obtained is in line with the works reported in the literature [21], [22]. With 0.02 mm thickness of Hastelloy, even though the magnitude of strain has reduced, the trend remains the same As compared to the 0.05 mm case, with 0.02 mm thickness of Hastelloy, the induced strain is almost half.…”

Second-generation high-temperature superconductors, being brittle, need to be deposited on a substrate and converted to tapes with additional reinforcement layers. These tapes are wound on a core to make superconducting wires and cables. The mechanical loads during bending, twisting, winding, etc., can degrade the superconductor. It is necessary to determine the straininduced during these processes. Variations in induced strain with bending of superconductors have been investigated analytically and numerically for various configurations of Rare-Earth Barium Copper Oxide (REBCO) tape. The numerical simulation has been carried out using COMSOL Multiphysics software; the analytical examination of the effect has been performed applying the Flexure formula. The geometrical configuration of the superconducting tape is varied in terms of the bending radius, the thickness of constituting layers made of Hastelloy and copper. The results showed that the variation in the thickness of the substrate has a large influence on the induced strain. Electrical performance analysis is also carried out using the power law of strain dependence and the 5% critical current degradation point is noted. Results of these numerical and analytical investigations are expected to help in finding out critical parameters to avoid degradation while being in use.Index Terms-Bending, CORC cable, high temperature superconductors, intrinsic axial strain, REBCO tapes.

“…The effect of different type of mechanical load on the degradation of REBCO tape and cables are carried out by different researchers [4][5][6][7][8]. Winding of REBCO tape over the central core induce the combined effect of tension torsion and bending load on the REBCO tape [9]. Extensive simulation study on the winding of REBCO tape over the central core is done by K. Wang et al and Ashok K.B.…”
