Cross bore geometry configuration effects on stress concentration in high-pressure vessels: a review

Effects of Factors That Influence Out-of-Plane Lateral-Torsional Buckling on Freestanding Circular Arches

“…In engineering practices, these techniques have a common trend of implementation to analyze material applications. ese techniques can be applied alternatively depending on the need, availability, and complexity of the problem [47]. e techniques have different submethods of applications based on different assumptions and the level of accuracy needed.…”

“…Numerical methods are considered as approximate mathematical procedures [47]. ese techniques are established for cases whereby no exact solution exists or intractable cases like solving simultaneous equations with many unknown variables, that is, 20. e solutions generated using numerical methods are considered as approximate solutions [51].…”

Effects of Geometric Stress Concentration in the Design of Thick Compound Cylinders- A Review

“…Stress concentration is caused by the presence of any form of discontinuity in a structure. A discontinuity can either be in the inform of load, metallurgical, geometrical, or a combination thereof, alter the otherwise uniform stress distribution across the structure (Nziu and Masu, 2019a). This alteration of uniform stress distribution leads to the creation of high-stress concentration particularly in the neighborhood regions of the discontinuity (Cole et al, 1976).…”

“…Another review (Nziu and Masu, 2019a) of the effects of geometry configuration in a cross bore on SCFs in highpressure cylinders or vessels has been done. The paper established that studies conducted on the ideal combination of geometric design parameters of cross bore size, location, shape, obliquity, and thickness ratio, that gives minimum stress concentration in thick cylinders were non-existent.…”

“…Therefore, oblique or inclination of cross bores refers to placing cross bores in the longitudinal axis of the cylinder (Nziu and Masu, 2019a) Research work on stresses of an oblique hole in a thick flat plate that is exposed to constant uniaxial tension has been done (Stanley and Day, 1990). Experimental work was carried out on nominal plate thickness having a hole diameter varying from 1.33, 2.0 to 3.0, with obliquity angles ranging from 0 0 , 15 0 , 30 0 , 45 0 to 60 0 , and the load applied to directions of 0 0 , 30 0 , 60 0 and 90 0 about the major axis of the surface ellipse.…”
