Examine the results of the progressive fatigue analysis.
Now that you have completed the progressive fatigue analysis using Simulation Composite Analysis, the focus of the discussion will be centered around viewing and interpreting results. Viewing results from a progressive fatigue simulation is very similar to viewing results from a traditional Simulation Composite Analysis static progressive failure analysis. The meanings of the solution-dependent variables are modified for fatigue analyses, with the new meanings specified in the .mct file accompanying the completed analysis. Refer to the Simulation Composite Analysis User's Guide for further details of each solution-dependent variable (Progressive Fatigue Results and Appendix C).
After the job has completed, start ANSYS APDL and open ASCA_Tutorial_4.db. Click
and select ASCA_Tutorial_4.rst. Click to read the last set of results.The plot of SDV2 depicts the cycles to failure for each element. In the same manner that SVAR2 was plotted, a plot of SVAR1 can be made which will show the damage state of the model to verify that failure has occurred. You can also use nodal displacements and the cycles to failure for unfailed regions of the model reported in the ASCA_Tutorial_4.txt file to create a plot of cycles to global structural failure as seen below.
