Abstract
In this paper, the ANSYS general purpose finite element computer aided design program was used to perform a series of stress analyses for shells with heads of various shapes.
The analysis included maximum discontinuity stresses, stress contours and displacements induced in axisymmetrical shells subjected to internal pressure loading; especially at the junction of the cylinder and heads of various shapes.
CONICAL SHELL finite elements and TWO-DIMENSIONAL ISOPARAMETRIC finite elements were used in the analysis. The results of the analyses compared very favorably with solutions derived from membrane and bending theory solutions for pressure vessels.
The effect of longitudinal and hoop stresses was investigated as well as the effect of the head shape end closure in pressure vessels.
This approach enables the designer to obtain a deeper understanding of the relationships of the generator, the shape of the head thus generated, and the discontinuity stresses at the junction.
