Abstract
The TEXTOR vacuum vessel represents a steel torus shell with numerous radial and vertical ports. The induced eddy currents as well as electromagnetic forces in the vessel during plasma disruption have been calculated using the TYPHOON code. For the purposes of the stress analysis the vessel shells are modeled with shell elements. The bellows and flanges are built with 3D anisotropic solid elements. To apply the calculated electromagnetic forces to this model a special interface code has been developed. Stress analysis has been performed in two steps of loading in reference to symmetry and antisymmetry boundary conditions and the results have been superimposed.
