Fatigue Process

Create or open a fatigue analysis setup process.

The fatigue process template is a workflow-based process manager framework. It is supported on the HyperWorks Desktop environment. It allows you to set up a quick OptiStruct solver deck for fatigue simulation with minimum intervention. It also allows you to submit the OS job on the local workstation and supports post processing of fatigue results such as life & damage within the same environment.

The fatigue process manager supports both S-N (Stress-Life) and E-N (Strain-Life) methods. In addition, it also supports Factor of Safety, as well as spot and seam weld fatigue analysis setup. The fatigue process manager consists of the following steps:
  • Importing the model
  • Creating the fatigue subcase
  • Defining fatigue analysis parameters
  • Defining fatigue elements and SN/EN properties
  • Defining the load-time history and the loading sequence
  • Submitting the job
  • Viewing the results summary and launching HyperView for post-processing
Restriction: Only available in the OptiStruct solver interface.

Create New Session

In this step you will create a new fatigue process session.

  1. From the menu bar, click Tools > Fatigue Process > Create New.
    The Create New Session dialog opens.


    Figure 1.
  2. Type a name for the new fatigue analysis setup process and save it to your working directory.
  3. Click Create.
    The panel area displays similar to the following image.


    Figure 2.
  4. In the Model file path field, browse to the location of your model file then click the Import button.
    The model displays in the graphics area.
  5. Click Apply to move on to the next step in the process.
    The Process Manager browser will move to the Fatigue Subcase step and the panel displays similar to the following image.

Load Existing Session

As an alternative to creating a new fatigue process session, you can load an existing session if you have one already saved.

  1. From the menu bar, click Tools > Fatigue Process > Load Existing.
    The Process Manager browser opens.
  2. In the Open dialog, select an existing fatigue analysis process file (*.pmi) and click Open.
    The session will be loaded along with the model file.
  3. Click Apply to move on to the next step in the process.
    The Process Manager browser moves to the Fatigue Subcase step and the panel displays similar to the following image.
