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
