Evaluate strength results

This procedure assumes you have created an event and applied excitations to your model. These steps describe how to evaluate the dynamic strength results.

1. In the Simulation Navigator, right-click your Event node and choose Evaluate Contour Results→Strength.

2. Select one or more elements on the model to specify the location of the evaluation. Use the Selection Method options to easily select all elements in an edge, body, mesh, and so on.

3. For Transient and Quasi-Static events, under Stress Criteria, choose the method (Von Mises, Maximum Principal or Minimum Principal stresses) to use in determining the strength failure index for the requested elements. The software uses the maximum values of effective stress in the time history.

4. Under Stress Option, choose the method for calculating and storing the strength results:To store results for every node on the selected elements, select Node on Element.To store only the most conservative value for each selected element, select Element Maximum.

5. For response spectrum and DDAM events, the software calculates the peak values by combining the peak response of each mode and each excitation. Under Evaluation Settings, select the Evaluation Method for performing this combination. For more information, see Evaluate Strength Results dialog box.

6. Under Material Properties, select the method the software uses normalize the maximum stress in the event, using either the Ultimate Strength or Yield Strength values defined in each element's material properties. To override the material properties, select Override Material Properties and enter the new value in either the Ultimate Strength or Yield Strength box.

7. (Optional) Under Preview, select the options for the preview evaluation.

8. Click to preview the results. Select the viewport in which to preview the results.

9. In the Evaluate Strength Results dialog box, click OK to generate the strength results.

10. View the results in the Post Processing Navigator, under the Event node. They are listed under the heading Strength Safety Factor, although the results are reported as the strength failure index (as the index number approaches 1, there is a higher likelihood of failure in that area of the model).
