| Abstract |
The application of the Ritz method is justified in relation to the
boundary value problems of the theory of geometrically and physically
nonlinear thin elastic non-shallow shells. A distinctive feature of the
paper is that we use some special function space, other than
the usual spaces of displacements and stresses, and
express the displacements and strains through some auxiliary functions.
Boundary value problems for non-shallow shells whose middle surface is
a surface of revolution or a convex surface having an involute,
were considered in [1-4]. In this paper, we propose a method for the
investigation of arbitrary non-closed non-shallow shells of a nonzero
Gaussian curvature. The shells are supposed to be rigidly fixed along the
entire boundary. We obtain equations for which the following
conditions hold: there exists at least one
point of absolute minimum for the total energy functional for the
"shell-external forces" system; approximate solutions converge to
a minimizer of this problem; the minimizer is a generalized solution of
the equation obtained from the variational Lagrange principle. |
