How to use stress analysis in Autodesk Inventor to test your parts.

This is an intro to Autodesk Inventors stress analysis feature.  When making parts and assemblies it is extremely important to know where the critical stress and fail points are in your design.  The stress analysis feature removes the guesswork and over engineering in your design.  

The two things needed to start this process is a Inventor Part or Assembly file, and some estimated or actual calculated input forces for your part.

Let's start by opening your Inventor part file.

Step 1: Starting a stress analysis

To start a new stress analysis go over to ENVIRONMENTS tab on your ribbon, click on it and on the left side of your screen you will see the stress analysis feature (rainbow colored cube).  Click on the icon and then click on create simulation.  That will bring up a screen of initial settings.  You can choose a static analysis or modal analysis.  

The simple definition of static would be your main input force which is not affected by time/temp/atmospheric pressure.  Modal is dynamic forces (vibration) that will have secondary effects on your part. 

For this trial we are going to use a static stress analysis.  Select it and click OK.

Step 2: Defining your parts material.

Defining what type of material your part is determines the amount and types of forces it can handle before it fails.  This should be the first step before you continue on with your test.  Under your ribbon you will have a materials section with an icon that says ASSIGN, click on this.  It will bring up a pop up window displaying your part material.  If you already defined what the material was when you made your part, that material will be displayed.  If you haven't yet defined it, click on materials and select the desired one.  When you select a material you can also double click on it to see the preset settings for that type if you need to verify or change them.

Once you are happy with your material and settings click OK and then we will be ready to define our constraints and input forces.

This would be great for testing uke and guitar neck designs. Thanks for the introduction!

it's a great soft, but, unfortunely doesn't work on linux.

Great instructables by the way.
