Fracture Mechanics and Fatigue Crack Growth Analysis Software |
NASGRO® is a suite of programs used to:
-
Analyze fatigue crack growth and fracture
-
Perform assessments of structural life
-
Process and store fatigue crack growth properties
-
Analyze fatigue crack formation (initiation)

| In 2003, NASGRO® Version 4.0 received the NASA Software of the Year Award and an R&D 100 Award from R&D Magazine as one of the 100 most technologically significant new products of the year. | |
NASGRO Version 5.2 was released in January 2008.
The next meeting of the NASGRO Consortium will be held at SwRI on May 20-22 2008.
NASGRO is licensable for a fee. Over 150 single-seat licenses to NASGRO have been obtained by a wide range of users from different industries.
The materials database includes a large set of crack growth rate and fracture toughness data. The stress intensity factor library provides models for over 60 different crack geometries.
NASGRO was originally developed at the NASA Johnson Space Center to perform fracture control analysis on NASA space systems. A growing interest in NASGRO among a variety of industrial users motivated NASA to develop a new partnership with industry. In July of 2000, NASA and Southwest Research Institute® (SwRI®) signed a Space Act Agreement under which SwRI formed and manages a consortium to provide guidance and support for future NASGRO development and user services. The NASGRO Consortium is now in its third three-year cycle (2007-2010).
