Properties of numerical solution of the deformation and stability problem in shallow conical shells under external pressure
Journal Title: Roads and Bridges - Drogi i Mosty - Year 2016, Vol 15, Issue 2
Abstract
The paper presents an analysis of a numerical solution in the ANSYS software to three problems related to determination of deformations and stability of closed shallow conical shells under external pressure: 1) linear (bifurcation) problem of determining the critical pressure; 2) geometrically non-linear problem of shell deformation and buckling to determine the limit pressure using axisymmetric finite elements (FE); 3) solution to the same problem as set out in 2, yet using 4-node shell elements. The solutions presented in the paper concern the stationary state of a simply supported and fixed shell. Shallow conical shells are applied as load bearing and protective elements of bridge structures.
