Clearly, there can be no rigid body motion other than x-translation of the plate. Applying boundary conditions and loads to the model. The reason the stress field is altered is because the presence of the hole requires that the stresses in the plate redistribute themselves in order for any part of the structure to remain in static equilibrium. How to Analyze the plate with a central hole in ANSYS APDL. Apply loads and boundary conditions. Previous works indicate that in a perforated plate there is a reduction in the ultimate stress if compared with a plate without perforations; but, surprisingly, in some cases an increase in the magnitude of the elastic critical stress can be observed when a per-forated plate is compared with a non-perforated plate (Cheng and Zhao, 2010).
