NASGRO is a suite of computer programs used to analyze fracture and fatigue crack growth (FCG) in structures and mechanical components. The software is developed jointly by Southwest Research Institute® (SwRI®) and the National Aeronautics and Space Administration (NASA) under a Space Act Agreement, with additional support from the NASGRO Consortium and the Federal Aviation Administration (FAA). NASGRO is the most widely used fracture mechanics and FCG software in the world today, including many applications for aircraft, spacecraft, rotorcraft, gas turbine engines, pressure vessels, and other structural components.
NASGRO consists of integrated modules with user-friendly graphical interfaces that:
- Calculate stress intensity factors
- Calculate crack growth life and critical crack size
- Store, retrieve, and curve-fit FCG and fracture toughness data
More information about NASGRO features and capabilities is available here.
The current production version of NASGRO is 9.1 (released on May 16, 2019). More information about this release and new features in other recent versions is available here. A PDF flyer describing the current version can be downloaded here.
NASGRO training courses are taught twice each year in San Antonio, Texas, and occasionally in Europe. Training courses can also be taught at client sites in the U.S. or other countries.
