Hyperlife hand calculation

Mehmet_21515

Hi all, 

my question is about hyperlife damage calculation process for strain-life state. I want to do some hand calculation to estimate fatigue life and obtain same results with Hyperlife. I am using .h3d file as my input for calculations.

1. How does Hyperlife calculate related strain value to use at E-N graph? I am using same formulas in help document however I am getting different values.
