Abstract
The aim of this study was to investigate the impact of shape on cross-bored compound cylinders, particularly circular and elliptical configurations. The analysis was conducted with a uniform pressure of 88.494 MPa. It was found that a radial circular cross-bore with a cross-bore size ratio of 0.1 resulted in the lowest Stress Concentration Factor (SCF) of 2.66. Subsequently, a thorough examination of 12 different diameter ratios for the elliptical-shaped cross bore, ranging from 0.5 to 10, identified the minimum SCF value of 1.33, which occurred at a diameter ratio that was then used for further analysis. The mentioned SCF value represented a 24.81% reduction in the pressure-carrying capacity of the compound cylinder compared to a similar plain compound cylinder. In a broader comparison between circular and elliptical cross bores yielded lower hoop stresses than their circular counterparts.
