Analysis Type(s): Static Analysis (ANTYPE = 0) Element Type(s): Axisymmetric Structural Shell Element (SHELL51) Input Listing: vm13.dat Test Case A long cylindrical pressure vessel of mean diameter d and wall thickness t has closed ends and is subjected to an internal pressure P. Determine the axial stress σy and the hoop stress σz in the vessel at the midthickness of the wall.

ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–41 VM13 Analysis Assumptions and Modeling Notes An arbitrary axial length of 10 inches is selected. Nodal coupling is used in the radial direction. An axial force of 5654866.8 lb ((Pπd2)/4) is applied to simulate the closed-end effect.
