The central solenoid of the ohmic heating system for a tokamak fusion device.
An axisymmetric problem of magneto-structural coupling.
The solenoid consists of 80 superconducting coils fixed in common plastic structure. Due to mirror symmetry one half of the structure is modeled.
Copper of coils:
Young's modulus E = 7.74·1010 N/m2;
Poisson's ratio ν = 0.335;
Maximum allowable stress: 2.2·108 N/m2.
Young's modulus E = 2·1011 N/m2;
Poisson's ratio ν = 0.35;
Maximum allowable stress: 1·109 N/m2.
