A long cylindrical membrane container of diameter d and wall thickness t is subjected to a uniform internal
pressure P. Determine the axial stress σ1 and the hoop stress σ2 in the container. See VM13 for the problem
sketch. Figure 20.1 Cylindrical Membrane Problem Sketch Material Properties
E = 30 x 106 psi
υ = 0.3 Geometric Properties
d = 120 in
t = 1 in Loading
P = 500 psi Analysis Assumptions and Modeling Notes
An arbitrary axial length is selected. Since the problem is axisymmetric, only a one element sector is needed. A
small angle Θ = 10°...
