View Long Term Heat Aging Plots

Understand a material's thermal endurance and Arrhenius parameters by visualizing Long Term Heat Aging (LTHA) plots.

1. Select a material.
   The Info tab displays general information about the selected material.
2. Click Plots.
   The Plots list is displayed.
3. Select the LTHA Stress at Break plot from the list.
   The selected plot is displayed.

4. Click on the plot options menu.
   Tip: Hover over the plot area to view the plot options.
   The LTHA Stress at Break and Thermal Endurance plots are displayed.

5. To analyze the material data, enter a threshold value in Define threshold in %.
   The Thermal Endurance points are displayed. If a minimum of three thermal endurance points are intersected then a regression line is drawn automatically and it calculates the Arrhenius Parameter for a material.

6. Select the Percentaged Representation check box.
   The thermal endurance result is calculated in percentage with the 100% stress applied to the material at different temparatures.
