Set up a Static Stress analysis

Run a static stress analysis to determine the likelihood of your design failing under load conditions.

Note: If you want to run further analysis in Ansys products, you can send your study to Ansys Mechanical or Ansys Discovery or export it to Ansys Setup.

Workflow of a Static Stress analysis

  1. Open or create a model.

  2. Access the Simulation workspace.

    • The first time you enter the Simulation workspace, the New Study dialog appears automatically.

  3. In the New Study dialog, set the Study Type to Static Stress.

  4. Optionally, click settings icon Settings in the upper right corner of the large image in the New Study dialog to specify settings for the analysis.

    Note: From the Results tab, select Manage > Settings to specify or modify the Settings any time using a separate Settings dialog.

  5. Click OK.

  6. Optionally, use the Simplify contextual environment to make simulation-specific changes to the model, preserving the production model:

    • Remove unnecessary features that only complicate the analysis and do not provide useful information. See Model Simplification (Defeaturing).
    • Take advantage of Symmetry when appropriate to reduce the simulation model size and solution time. Symmetry can also facilitate constraining a model in a way that provides full stability but does not at all impede the natural deformation.
    • Split faces to confine loads or constraints to a only portion of a larger face.

  7. Optionally, activate Remove rigid body modes within the study Settings dialog.

  8. Apply materials.

    • Simulation materials may differ from the materials defined in the Design workspace.

  9. Apply constraints.

  10. Apply loads.

  11. It is a good idea to generate the Mesh, though the model is meshed automatically when you solve the simulation. If you are not satisfied with the mesh appearance, adjust the size parameters or apply local refinement. Repeat this step until you are satisfied with the mesh.

  12. Solve, though the model is meshed automatically when you solve the simulation. If you are not satisfied with the mesh appearance, adjust the size parameters or apply local refinement. Repeat this step until you are satisfied with the mesh. See the simulation.

  13. Review the results:

    • Safety factor
    • Stress
    • Displacement
    • Reaction Force
    • Reaction Moment
    • Strain
    • Contact Pressure
