000014267 520__ $$2eng$$aThe mechanical behaviours and electric properties of multi-filament twisted superconducting (SC) strands are investigated based on a 3D FEM model with consideration of damage of filament, the initial thermal residual stress, etc. The distribution of the damage of the filaments and its evolution and the movement of the neutral axis caused by it are studied and displayed in detail. Besides, the normalized critical current of SC strands under bending load is also calculated based on the invariant temperature and field strain functions. The non-negligible influences of the pitch length of the filaments on both the mechanical behaviors and the normalized critical current are discussed. A MULTI-FILAMENT TWISTED FEM MODEL FOR SUPERCONDUCTING STRAND As the basic structure generating the magnetic confinement for the fusion plasma in the International Thermonuclear Experimental Reactor (ITER), the strand works under strong magnetic field (12 T) and low temperature (4 K). Due to the current carried herein and the change of the temperature, the strand is always subjected to the bending (Lorentz force) and axial (thermal expansion) deformation, which will lead to the degradation of the superconductivity.
