MATHEMATICAL MODEL OF DISCRETISATION OF CYLINDER WITH ELLIPTIC BOTTOM FROM HETEROGENEOUS MATERIALS

The algorithm for calculating arbitrary articulated shells with different physical - me- chanical characteristics based on the finite element method with using of the interpolation of scalar and vector displacement fields is presented. As part of the sampling, rectangular curvilinear finite elements of eighteen degrees of freedom in the node were used. The analysis of VAT thin shell of dissimilar materials in the form of a cylinder with elliptical bottom was fulfilled
