Inventor allows carrying out the stress analysis for a particular part. The calculation is done through the finite elements method.

Let us draw a circle with diameter of **20 millimeters,** with the center on the origin. Finish sketch.

Perform the **Extrude** operation. Enter the distance of **300 millimeters,** press **OK.** Name this part **Shaft** and save it.

The material is **Steel, Carbon.**

**Right click** on the name of the part and open **iProperties.** On the tab **Physical** ensure that selected material is **Steel, Carbon.** Close the window.

On the **Environments** tab select **Stress Analysis.**

You should have an available Stress Analysis menu. Press **Create simulation,** rename it to **Calculation of bending.** For now, leave the other settings unchanged.

Press **OK.**

First, check whether the software assigned the correct material for calculation. Open the **Assign materials** window. Here we see that the field contains correct value: **Steel, Carbon.**

Here we can override the material and choose one of available materials. Press **OK.**

Next, we specify the constraint for our calculations. Select **Fixed constraint** and specify the end planes of the shaft.

**Apply.**

On the **Loads** panel select **Force.** Set the location of the force on the body of the shaft.

Check **Use vector components.** Enter the exact force value of 1000 – **1000** Newtons on the **Y** axis. Enter **-1000** to choose the opposite direction of the force. **Apply.**

In the browser area, you can see the corresponding folders with loads and constraints, you can edit them at any time.

Now when you have specified the loads and fixed constraints, let us deal with the ways to separate a part into the finite elements.

The finite elements method is a method when a whole body is divided into the finite number of figures, tetrahedrons.

On the **Mesh** panel there is an item **Mesh view.**

To get more detailed results, you need to set up the mesh.

Click on the **Mesh settings.** Here you can specify the average element size. Enter **0,05,** the maximum element size is **0,1,** leave grading factor unchanged, maximum turn angle is **20°.**

Depending on the parameters of your hardware, you can specify larger or smaller values. This will directly impact the accuracy of calculations.

To perform calculations press **Simulate.** Than press **Run.**

Three-dimensional constraints and loads are created in several directions. These multi-direction loads are added to get the equivalent load, which is also knows as **von Mises stress.**

The result of calculation is displayed as the exact von Mises stress.

You see the result as coloring of the part into several colors. Each color has its own load. Blue means the smallest load, while red is the maximum one. On the left part of the screen, you may see a graph, where you can compare a color to its value.

**Double** **click** in browser area to select other obtained results.

You can view the first **principal stress,** the **third principal stress, displacement,** and **safety factor.** In addition, you may view **Stress, Displacement,** and **Strain** in every direction.

If you click on the **Mesh view,** you can see that the part is divided into the smaller elements.

On the **Result** panel, you can view the load animation.

You can specify the place for the probe and view the results of calculation for every point on the surface of your part.

On the **Display** panel you can enable the display of the minimum and maximum results of calculation.

With the adjustment option, you can select a multiplier to view more detailed results.

The **Report** panel is used to create reports on all the results of calculation. It is saved in the **HTML** format and contain all calculation data.

Here you see all loads, constrains, materials, and the results of calculations.

Finish stress analysis and save the part.
