POWER-SERIES STRESS-ANALYSIS OF SOLENOID MAGNETS

An analytical solution for the stress analysis of superconducting sole noids is given which reflects the full spatial variation of Lorentz bo dy forces and includes shear stress components. The solution is based on power series expansions of the Lorentz body forces and the displace ments which in turn gives the strains and stresses, including shear st ress components. This solution is applicable to the windings and reinf orcement layers of magnets and is compared to a finite element method using a 7 T sample magnet with reinforcement.
