KIHIU, J.M.  e  MASU, L.M.. The effect of chamfer and size on the stress distributions in a thick-walled cylinder with a cross bore under internal pressure. R&D j. (Matieland, Online) [online]. 1995, vol.11, pp.73-78. ISSN 2309-8988.

The hoop stress and stress concentration factor distributions in a closed ended thick-walled cylinder with a chamfered cross bore under internal pressure were investigated. The finite element method of stress analysis was used for this study. The effect of changing chamfer angle, for a fixed chamfer size, on the hoop stress and stress concentration factor distributions was investigated. The effect of changing the chamfer length, for a fixed chamfer angle, on the hoop stress distributions and stress concentration factors was also investigated. The optimum chamfer angle and chamfer length for any cylinder configuration was established. The study revealed that adding chamfers to cross bores causes a redistribution and reduction of the stresses attained in internally pressurized thick-walled cylinders. For a thick cylinder of a given thickness ratio and cross bore diameter, it was observed that the stresses were a minimum at a specific chamfer angle and size.
