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.
