Abstract

In this paper a unified numerical design algorithm is described which enables the selection of the shape of the meridian of shell of revolution (nonlocal stress concentration problem) or the shape of the boundary of the notches in the shell (local stress concentration problem) necessary to keep the peak of effective stresses to minimum as it is possible. The design procedure is the combination of the Computer Aided Geometrical Design (CAGD) mathematical methods tor the shape definition, of the Finite Element Method (FEM) used for the analysis of the stress field. the Direct Sensitivity Analysis (DSA) for the objective and stress gradient computations, which is related to the analysis method, helped by the Sequential Linear Programming (SLP) used as optimisation procedure.
