In this tutorial, the analysis of an open-ended cylinder with internal
pressure is presented. The unknown to be found is the stresses in a thick
open-ended steel cylinder (shown) with an internal pressure (such as a
pipe discharging to the atmosphere).
Material properties: Young’s modulus: E = 30 × 106 psi, Poisson’s
ratio: ν = 0.3
Geometry: Internal radius: r = 5 in, external radius: r = 11 in, length:

arbitrary, for segment of a long, open-ended cylinder
Loading: Internal pressure: p = 1,000 psi.
Constraints: uz = 0 on a radial surface parallel to the x-y plane,
ux = 0 on a radial surface parallel to y-z plane, uy = 0 on top/bottom
surface (prevent rigid body motion in y-direction)
