Stress concentration at crossholes in thick cylindrical vessels

Makulsawatudom, P. and Mackenzie, D. and Hamilton, R. (2004) Stress concentration at crossholes in thick cylindrical vessels. Journal of Strain Analysis for Engineering Design, 39 (5). pp. 471-481. ISSN 0309-3247 (http://dx.doi.org/10.1243/0309324041896506)

Abstract

Elastic stress concentration factors (SCFs) for internally pressurized thick cylindrical vessels with radial and offset circular and elliptical crossholes are presented. Three forms of intersection between the crosshole and main bore are considered: plain, chamfered and blend radiused. The minimum SCF was found to occur for the plain intersection configuration, with the peak stress at the crotch corner between the main bore and crosshole on the longitudinal plane of symmetry. Incorporating a chamfer or blend radius at the intersection reduces the stress concentration at the main bore but introduces higher peak stress elsewhere in the chamfer or blend region.
