ABSTRACT
The analysis of pressure hull is of great importance among structural engineering
due to the complexity involved in the collapse mechanism of stiffened shell
structures. Due to this complexity, only a limited amount of test data was available to
evaluate the effect of the external pressure on the stability of stiffened shell structure.
The proposed work considers theoretical study and experimental test data of the
pressure hull. Uniformly ring stiffened cylinder, dome and conical elements of a
pressure hull are considered. For the same experimentally considered model, a
numerical study using Finite Element Method (by ABACUS program) is also
presented. The obtained experimental and numerical results are compared.
