... in the median section and in the junction section between the elbow and the straight pipe. Elbows considered here have a bend angle α c = 45 , 90, and 180 deg and show a ratio r m / t between 5 and 20 and a parameter λ up to 1. Analytical expressions are proposed to fit the membrane and bending components...

...Shuguang Li; John Cook This paper is concerned with the membrane shell analysis of filament overwound toroidal pressure vessels and optimum design of such pressure vessels using the results of the analysis by means of mathematical nonlinear programming. The nature of the coupling between overwind...
