magnetic field in modern tokamaks. Nb3Sn superconductivity depends not only on
temperature and magnetic field as eg NbTi, but also on the strain state of the strands inside
the conductor. It is hence very important to be able to predict the mechanical deformations
due to manufacturing processes and operating conditions. The conductors for ITER, the
International Thermonuclear Experimental Reactor currently under construction, have a …
