Stress concentrations due to axial loading applied to axisymmetric internal projections on hollow tubes

Abstract

Stress concentration factors due to the axial loading applied to axisymmetric, internal projections on hollow tubes have been obtained by using the finite element method. A range of tube and projection dimensions and fillet radii have been covered by the investigation. It was found that all of the results could be presented on just two graphs. Hence the stress concentration factor, for any shape within the range investigated, can be quickly determined. A simple relationship between stress concentration factor and ‘load position’ was also found to exist.
