COMPARISON OF DIFFERENT PLANE MODELS IN FINITE ELEMENT SOFTWARE IN STRUCTURAL MECHANICS Behrooz Yazdizadeh

In solution of plane problems of mechanics there are several elements used in finite element software. In ANSYS – one of the best finite element software – there are about six type of elements. We consider different Plane Models in simple bending problem and compare the various results to distinguish the type of elements, which are suitable for solving the problem under consideration. Comparing results with analytical solutions shows that the Plane 42 and 82 models are the most suitable ones among the others. Also results in Plane 42 with usual mesh is closer to the same problem solution with fine mesh than Plane 82 in the same case.
