HL-T: 1040 Factor of Safety (FOS)

In this tutorial you will:
  • Import a model to HyperLife
  • Select the FOS module and define its required parameters
  • Create and assign materials
  • Assign load histories for scaling the stresses from FEA subcases
  • Evaluate and view results
Before you begin, copy the file(s) used in this tutorial to your working directory.

Import the Model

  1. From the Home tools, Files tool group, click the Open Model tool.


    Figure 1.
  2. From the Load model and result dialog, browse and select HL-1040\Springlink_FOS.h3d for the model file.

    Tip: Expand the width of the dialog to view a clearer picture of the plot.
  6. On the bottom half of the dialog, set the radio button to Manual for event creation and click three times to create three event headers.
  7. Drag and drop Subcase 1 under Event_1, Subcase 2 under Event_2, and Subcase 3 under Event_3.
  8. Drag and drop the Block file under load1 onto the Channels field of all three subcases.
  9. Activate the checkboxes for the three events.
  10. Set LDM to 1.0, Scale to 3.0 and Offset to 0.0 for Subcase 1.
  11. Right-click on the Scale field of Subcase 1 and select Apply value to all events.
