5.4.2.9.0 Assign Precrack Values
Specify these parameters if the specimen was precracked on another load frame. When the precrack
parameters are specified here, you can then skip Precrack Specimen in the Main Menu window.

5.4.2.10.0 Calculator
Use the Calculator to calculate the load to use for new specimens.You can also use the Calculator to calculate
stress intensity (K). Load is calculated from the crack size value and stress intensity (K) value. Stress intensity
(K) is calculated from the crack size value and load value.
Typically, you use the Calculator after the crack size is checked. If the crack size check is performed, the
software supplies the crack size value for the Calculator. You can also enter a crack size value manually.
You must enter the load or stress intensity value manually.
The following table lists the load P parameters.
