THE SIMPLIFY OF THE FEM ANALYSIS OF THE MUTI-LAYER COMPOSITE CYLINDERS

The problems of muti-layer composite cylinder frequently are regarded as ones of solids of revolution. It's contact boundaries are unchanging, and the neglect of friction is permitted. By virtue of the simple compatible relation of deformation between cylinders, it's analysis of FEM can be simplified greatly, and this analysis has the advantages of less computing effort and better computing accuracy.
