The central solenoid of the ohmic heating system for a tokamak fusion device.
Problem Type:
An axisymmetric problem of magnetostructural coupling.
Geometry:
The solenoid consists of 80 superconducting coils fixed in common plastic structure. Due to mirror symmetry one half of the structure is modeled.
Given:
Copper of coils:
Young's modulus E = 7.74·10^{10} N/m^{2};
Poisson's ratio ν = 0.335;
Maximum allowable stress: 2.2·10^{8} N/m^{2}.
Plastic structure:
Young's modulus E = 2·10^{11} N/m^{2};
Poisson's ratio ν = 0.35;
Maximum allowable stress: 1·10^{9} N/m^{2}.
