ABSTRACT
The aim of the paper is to present a simple procedure to model a shell of revolution with negative Gaussian curvature by means of combined cylindrical and conical shells. Each shell is simply supported at the outer edges and subjected to uniformly distributed external pressure. It was assumed that the total volume and length of the combined cylindrical and conical shells are the same as in case of the shell with negative Gaussian curvature as well as the individual shells (cylindrical and conical) detect similar critical pressure. Modelling of the concave shell into three and five parts was analysed. The problem of shell modelling was solved by an iterative method. The results of calculation for the family of equivalent shells with negative Gaussian curvature are presented.
