It was used ANSYS Program in the case study, that describes the problem, a static analysis is carried out. Figure (4) shows the Von Misses stress distribution obtained with 24 bilinear quadrilateral elements. It should be noted here that 24 elements (41 nodes) for such a problem may not be sufficient for accurate results. Analyses with a denser mesh (129 elements and 185 nodes) using the same element type are also carried out. Their input files will be similar to that shown, but with more nodes and elements Figures (5) and (6) show the Von Misses stress distribution obtained using 96 (129 nodes) and 144 elements (185 nodes), respectively. Figure (7) also shows the results obtained when 24 eight-nodal elements (105 nodes in total) are used instead of four-nodal elements. The element types in ANSYS are for eight nodal, plane stresses. Finally, linear, triangular elements are also used for comparison, and the stress distribution obtained is shown in Figure (8).
