AN ACCOUNT OF REINFORCEMENTS IN A SHELL ANALYSIS BY VARIATIONAL-DIFFERENCE METHOD

A ribbed shell of a general form consisting from a skin, a position of points of the middle surface of which is determined by the orthogonal curvilinear coordinates ?, ?, and curved ribs, lying along coordinate linesareconsidered. At the moment, a classical approach is taken in the work to model ribs by the rod theory of Kirchhoff-Clebsch. A shell is described by the theory of thin shells of the Kirchhoff-Love
