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
Multipurpose Elite application 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.
