How to Perform a Stress Analysis in Autodesk Inventor
This tutorial will show you how to perform a stress analysis on a CAD model using Autodesk Inventor.
-
Step 1: Preparing the CAD Model
Creating or Importing the Model:
Open Autodesk Inventor and start a new project or import the CAD model you wish to analyze.
Geometry Verification:
Ensure the geometry of the model is correct, making sure there are no intersections or disconnected surfaces. Verify that all dimensions and details are accurate.
-
Step 2: Setting Up the Simulation
Starting the Simulation Module:
In the toolbar, go to the "Environments" tab and select "Stress Analysis."
Creating an Analysis Study:
Click on "Create Simulation" and select "Static Analysis." Name your study and click "OK."
Material Selection:
Choose the model material in the "Assign" tab and click "Assign Materials." Select the appropriate material from the library or create a new one with the desired properties.
Applying Constraints and Boundary Conditions:
In the "Constraints" tab, apply the necessary constraints to represent how the model is fixed or supported. In the "Loads" tab, apply forces, pressures, or displacements to the model, specifying the magnitude and direction of these loads.
-
Step 3: Mesh Generation
Mesh Settings:
Click on "Mesh Settings" to adjust mesh parameters such as element type and density. Then click "Generate Mesh" to create the model mesh and ensure it is sufficiently detailed.
Mesh Refinement:
Refine the mesh in critical areas if necessary to obtain more accurate results.
-
Step 4: Running the Analysis
Simulation Setup:
Review all settings and parameters before starting the simulation.
Executing the Simulation:
Click "Run" to execute the stress analysis. The execution time will vary based on the model's complexity and mesh density.
-
Step 5: Interpreting the Results
Viewing the Results:
After the simulation, view the results in the "Results" tab. Use tools like "Stress," "Displacement," and "Safety Factor" to examine different aspects of the analysis.
Detailed Analysis:
Examine the results in detail, focusing on critical areas of the model. Compare the results with design criteria to ensure the model meets safety and performance requirements.

Step 6: Reporting and Documentation
Creating the Report:
Generate a detailed analysis report by clicking "Report." Include all settings, results, graphs, and conclusions.
Creating the Report:
