Abstract: Endcaps on pressure vessels have stress concentrations which lead to fatigue crack initiation and growth during cycling of power generating plant. Finite element analyses of actual endcaps showed a current analytical method to be inaccurate. To develop a model, the maximum non-Mises stress was calculated across a range of geometries using over 380 finite element models. A new analytical method of calculating the stress concentration factor was developed based on the ratio of the von-Mises stress in the fillet to the hoop stress in the remote vessel wall. © 2017 Engineers Australia
