The deformation resistance of composite tapes was measured through compression tests. At room temperature, composite tapes were compressed and shaped at different deformation rates to different extents, and the real stress-strain curve of the composite superconducting tapes was obtained. Regression analysis was carried out on the curve using the Nonlinear Least Square Fitting (NLSF) method to acquire the parameters and coefficients regarding the curve, and a mathematical model for the deformation resistance of the composite superconducting tapes was built.
