Analyses of laminated beams for us in coil design

PDF Version Also Available for Download.

Description

Recent experimental data obtained from PLT has shown that equivalent beam theory is inadequate for predicting the deformation of large circular toroidal field coils. The PLT coils are much more flexible than equivalent beam theory predicts. The latest analyses have shown that shear plays an important role in the deformation of the PLT TF coils. This situation has indicated the need to analyze in explicit detail, the layer to layer behavior of simple laminated structures. The progress made to date in analyzing a laminated beam is summarized. By using variational techniques, the deflections and stresses in each layer of a ... continued below

Description

Recent experimental data obtained from PLT has shown that equivalent beam theory is inadequate for predicting the deformation of large circular toroidal field coils. The PLT coils are much more flexible than equivalent beam theory predicts. The latest analyses have shown that shear plays an important role in the deformation of the PLT TF coils. This situation has indicated the need to analyze in explicit detail, the layer to layer behavior of simple laminated structures. The progress made to date in analyzing a laminated beam is summarized. By using variational techniques, the deflections and stresses in each layer of a laminated beam are modeled. To date, reasonable results have been obtained for either deflection or stress separately but a single model that simultaneously gives good agreement for both deflection and stress has not yet been determined. Brief descriptions of the mathematical models used and the results obtained with each are presented. (auth)
