Estimate of the factor of safety of convex bottoms under uniform internal pressure

Abstract

This paper covers the derivation of engineering formulas in the State Standard Specification 14249-89 for the calculation of elliptical bottoms under uniform internal pressure, their numerical modeling of the stress-strain state by the finite element method and the comparative evaluation of the safety factor adopted in the State Standard Specification 14249-89 with the results of the experiment.

Keywords
