- W292301719 abstract "For the calculation of mechanical properties of large magnet systems in 3-dimensional space, a very fine subdivision of the magnet structure is necessary. In the finite element programms, this will lead to unacceptable long computing times and to the limits of computer-storage capacity. This limitation requires a simplification of the structure model. The objective of this work is to find such simplifications that still yield reliable results by the stress-strain analysis. This problem can be solved by the numerical method, called “numerical simulation”, by which an effective elasticity tensor will be obtained for a composite material. The structure can be arbitrarily complicated and may contain voids, e. g. cooling channels, which are weak elements for the structural analysis. The structure has only to perform a homogeneity condition, i. e. it must be possible to define a “respresentative volume element” (RVE). With the effective elasticity tensor, which can be found for such RVE, it is possible to calculate the average stress and with the interpolation of a surface displacement also the peak stresses in each point of the structure. A good agreement is found between experimental and theoretical moduli of elasticity. All the calculations are performed by the finite element computer code ASKA for one of the toroidal magnet coils from LCT (fig. 1). It appears necessary to evaluate not only average stresses, but in the most precise way the peak stresses, which could extend to several times the average values." @default.
