Viewing contour plots of specific state variables is the best way to evaluate the structural performance of the radiator tank. In particular, we'll examine SVAR13, the matrix failure index, and SVAR1, the rupture state.
- After the job has completed, return to the ANSYS Mechanical environment and select Solution from the model tree.
- Click and enter SVAR13 in the Expression box. SVAR13 represents the failure index of the matrix constituent.
- Set the Display Time to 0.01 seconds.
- Right-click the User Defined Result label and choose Rename.
- Name the result SVAR13.
- Repeat Steps 2-5 for SVAR1.
- Select Solution from the model tree once again and click and locate the radiatortank_ame.rst file.
- After the results are loaded, select the SVAR13 result.
- Change the deformation scale to 0.0 (Undeformed) and switch to the Graph tab.
- Click the play button on the Graph tab and monitor SVAR13 as the pressure is applied to the part. SVAR13 will give us an indication of how close the matrix material is to failure.
When the failure index reaches 1.0, failure has initiated. The first indication of failure occurs at step time 0.58 s.
- Now switch to the results for SVAR1. SVAR1 represents the rupture state of the composite material. A value of 1 means no rupture and a value of 2 means the integration point has ruptured.
- Step through the analysis to see how failure progresses in the tank.
