Abstract

A stress-strain state are investigated for thin-walled axisymmetric structures stressed with a set of point forces. Two approaches are used. First of them is based on using of the UAI/NASTRAN finite element program. This approach dominates presently in an engineering practice and when it is used any other techniques even are not considered. Second approach is based on analytical modeling. It is implemented using Matlab tools. A comparison of results obtained by means of these two approaches allows to formulate some recommendations for collaborate using of numerical and analytical tools. Such a kind of collaboration leads to more effective processes of stress-strain analysis for thin-walled structures.
