Unformatted text preview: and SHELL43 cases, since the problem is axisymmetric, only a one element Θ-sector is modeled.
A small angle Θ = 6° is arbitrarily chosen to reasonably approximate the circular boundary with straight sided
elements. The nodes at the boundaries have the UX (radial) degree of freedom coupled. In the SHELL43 model,
the nodes at the boundaries additionally have the ROTY degree of freedom coupled. ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–31 VM7
An ANSYS warning message is issued stating that element 1, (PIPE20 pipe element) has a radius to thickness ratio
less than 5. Because the model involves only axial loading, this does not affect the accuracy of the results. Results Comparison
