Description Parameter
Specify the maximum stress intensity desired
at the end of precrack activity. The initial Precrack Final Maximum
K
precrack Maximum K is 1.4 times the Final
Maximum K value.
5.6.2.4.0 KIC Parameters
In the KIC Parameters section of the main menu, you specify the KIC Force Ramp Rate, which is the rate
