Abstract :
The axial and torsional components of the stiffness matrix of superconductor core elements are derived taking into account the effects of the wrapping of superconductor strands around the internal insulation strip. It is shown that the inclination of the strands referred to the longitudinal axis of the superconductor produces a reduction of the axial stiffness and a considerable increase in torsional stiffness. Examples relating to superconductors proposed for the NET Toroidal Field Coil are provided. In that instance the strand transposition is carried out by roebling.
