Unformatted text preview: ance is attributed to the ability of the elements to properly handle bending and shear energy,
in contrast to the linear elements. 6. The percent error in energy norm for each test case is displayed against the tip displacement ratio to illustrate the general correlation between the two for this particular problem. The linear elements show
a patterned correlation between solution accuracy and the percent error in energy norm. For the quadratic elements the correlation pattern is similar. In both cases, the results illustrate that a considerable
bandwidth on norm values may exist at any desired solution accuracy level for problems under a variety
of load conditions with irregular element shapes. ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 2–35 VMD2: Barrel Vault Roof Under Self Weight
