AI Article Synopsis

  • Delamination in coated conductor tapes used in magnets and coils is a significant issue, primarily caused by excessive transverse tensile stresses.
  • Various methods are being assessed to evaluate the delamination strength of these tapes, with the anvil test being one of the key approaches.
  • The study explored how different sizes of upper anvils affect delamination strength, ultimately proposing optimal anvil sizes based on the specific application conditions.

Article Abstract

In coated conductor (CC) tapes used in magnet and coil applications, delamination due to excessive transverse tensile stresses is still one of the major issues that need considerations. Recently, several methods in evaluating the delamination strength of CC tapes are being used. In the case of anvil test, size of the anvils will be an important factor considering its applications (i.e., superconducting coil impregnation). In this study, delamination strength of CC tape was examined using different upper anvil sizes and their effects were discussed. Finally, reasonable sizes of upper anvil to be used were proposed considering the application conditions.
