Choose the Analysis tab from this box, and the values will be displayed.

You will notice that the Properties box shown below opens. It may take a minute before the database is searched. In order to inspect the values of the material properties assigned, double-click on Steel in the tree. The material property is now reflected in the tree. Use your cursor to pick the part on the screen at which time the OK and Apply Material buttons can be selected. The use of this icon opens the material database box shown next.ДЄnalysis of a Bent Rod with Solid Elements 2-5Д¬hoose the Metal tab on the top select Steel. Use the Apply Material icon from the bottom row of toolbars. The next step is to apply material properties on the part created. The result is the final part shown below. For Profile select the circle (Sketch.1) and for the Center Curve select (Sketch.2) as indicated. You will now use the ribbing operation to extrude the circle along the spine (path). , the screen and the tree should resemble the following figures. In the Sketcher, the spine should match the figure shown next. Draw the spine of theД«ent rod by using Profile and dimension it to meet the geometric specs. From the tree, select the yz plane and enter the Sketcher. Your simple sketch and the Constraint Definition box used to enter the correct radius are shown below. In order to change the dimension, double-click on the dimension on the screen and in the resulting box enter radius 1. In the Sketcher, draw a circle, and dimension it. The tree on the top left corner of the screen should look as displayed below.ДЇrom the tree, select the xy plane and enter the Sketcher. This will be the new part name throughout the chapter. From the Properties box, select the Product tab and in Part Number type wrench. In order to change the default name, move the cursor to Part.1 in the tree, right-click and select Properties from the menu list. See Note#1 in Appendix I.ДЄnalysis of a Bent Rod with Solid Elements 2-3 This moves you to the Part Design workbench and creates a part with the default name Part.1. From the box shown on the right, select Part. 2 Creation of the Part in Mechanical Design Solutions Enter the Part Design workbench which can be achieved by different means depending on your CATIA customization. These elements will be discussed in a later chapter. Hexahedral elements are also available on a limited basis in recent releases of CATIA. In general, the analysis of bulky objects requires the use of solid elements. Another important feature of parabolic elements is that they can fit curved surfaces better. On the other hand, the parabolic elements require more computational resources but lead to more accurate results. The linear tetrahedron elements are faster computationally but less accurate. Both are referred to as tetrahedron elements and shown below. There are two main types of solid elements available in CATIA V5, linear and parabolic. Although this problem is more efficiently handled with beam elements, we propose to use solid elements. The nominal dimensions of the rod are also displayed below. The steel rod has a Youngs modulus of 30E+6 psi and Poisson ratio 0.3.

1 Problem Statement The bent rod, shown to the right, is clamped at one end and subjected to a load of 2000 lb as displayed. Finally, the significance of the von Mises stress in design equation is discussed. No planes of symmetry exist and therefore model simplifications cannot be made. Introduction In this tutorial, a solid FEA model of a bent rod experiencing a combined load is created.
