Abstract:
Theoretical bases of methods and algorithms developed for the analysis of stability and post critical behavior of thin elastic shells. The problem of numerical analysis the nonlinear deformation processes of spherical domes under the uniform external pressure is discusses. Describes the computer algorithm based on the parameter continuation method, using the technique of subspaces of the of the control parameter subspace changing. Efficiency of the proposed approach is illustrated by same examples.
Keywords:Flexible shell, nonlinear deformation, stability, post critical behavior, numerical algorithm.
