Unformatted text preview: pan of the plate (target point 2). It can be seen that a significant number of elements through the plate thickness are required to accurately predict the bending stresses at the built-in edge for the solid elements. 7. The percent error in energy norm remains relatively high as the mesh is refined, with most of the error energy located at the built-in edges. This behavior is expected at built-in edges where point-wise inaccuracies in the solution occur. The displacement and stress results for which the refinement was targeted are quite good, despite the high energy error. 2–8 ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc.
