Abstract
Methods of calculating the non-homogeneous anisotropic rectangular shells with arbitrary fixation on the contour is set out, which is reduced to a boundary value problem, the solution of which is associated with considerable difficulties, since it is necessary to integrate a system of three partial differential equations with variable coefficient. To solve a system of equations in terms of displacements using finite difference method (FDM) in combination with different variations of analytical solutions. It is advisable to construct a numerical solution of the problem so that in difficult cases the support fixing and uploading solution sought, not directly, but in the form of amendments to the known solution for simple cases of reference to consolidate and uploading at finding the solutions which the analytical methods or the FDM with sparse mesh may be used. As examples the results of calculation for a series of square orthotropic shells with a fixed boundary under the action of a concentrated load are given.
