The problem is solved first using lower order 2-D structural solid elements (PLANE42) and then higher order 2D structural solid elements (PLANE82). For both cases, the membrane is modeled with one area and the automatic
adaptive meshing procedure is used to refine the mesh in the area of stress concentration (target location at
In the first case, the analysis is performed by running the problem until the SEPC (structural percent error in energy
norm) is close to 7.0 percent, whereas in the second case, analysis is performed until the SEPC is close to 5.0
percent. In the second case, the target value of SEPC is set less than the first case since higher order elements
are generally more accurate.
POST1 is used to obtain the final value of SEPC and the *GET command is used to obtain the tangential stress,
σy, at the target point D. Results Comparison
