NUMERICAL ANALYSIS OF THE STRESS-STRAIN STATE OF THE MEMBRANE SHELL WITH ACCOUNT OF GEOMETRICAL NON-LINEARITY

Abstract

The numerical procedures and results of analysis of rectangular membranes are presented. For the solution of the nonlinear problem the finite difference energy method and Newton-Raphson method are used.
