CATIA V5 FEA Tutorials
Introduction
In this tutorial, a solid FEA model of a bent rod experiencing a combined load is created. No planes of symmetry exist and therefore simplifications cannot be made. Finally, the significance of the von Mises stress in design equation is discussed.

Clamped end
The bent rod, shown to the right, is clamped at one end and subjected to a load of 2000 lb as displayed. The steel rod has a Young modulus of 30E+6 psi and Poisson ratio 0.3 . The nominal dimensions of the rod are also displayed below. Although this problem is more efficiently handled with beam elements, we propose to use solid elements. There are two types of solid elements available in CATIA V5: linear and parabolic. Both are referred to as tetrahedron elements and shown below.

linear
The linear tetrahedron elements are faster computationally but less accurate. On the other hand, the parabolic elements require more computational resources but lead to more accurate results. Another important feature of parabolic elements is that they can fit curved surfaces better. In general, the analysis of bulky objects requires the use of solid elements.
