NASMAT

NASMAT is a program that can be used to store, retrieve, and curve fit fatigue crack growth and fracture toughness data. For Version 4.1, the NASMAT GUI has been completely rewritten. The NASMAT database contains data for many materials in both English and metric (SI) units. Materials in the database are listed below.

The database contains more than 9,000 sets of data, including more than 3,000 sets of fatigue crack growth data and more than 6,000 fracture toughness data points. These data can be searched, plotted, and fitted to either the NASGRO® crack growth equation or a user-specified growth rate equation. They can also be entered in a growth rate table.
