Consortium Information

The NASGRO® computer code was first developed in the 1980s for fracture control analysis on NASA space hardware. Additional funding from NASA, FAA, and USAF in the 1990s supported substantial improvements for aircraft structures applications. The growing interest in NASGRO among many industrial users motivated NASA to develop a new partnership with industry. NASA and Southwest Research Institute® (SwRI®) signed a Space Act Agreement in 2000, renewed in 2009, under which SwRI formed a consortium of industrial NASGRO users to provide guidance and support for future NASGRO development and user services.

The NASGRO Consortium, which began in 2001, has been extremely successful. Fourteen major manufacturers of space structures, aircraft, rotorcraft, and gas turbine engines from nine different countries made an initial three-year commitment to consortium participation. The Consortium has been renewed for additional three-year cycles, and financial participation has grown as additional companies joined or expanded their membership. The sixth consortium cycle (2016–2019) is being formed and accepting new members.

The NASGRO Consortium enhances the long-term health of NASGRO by making the code more powerful and more popular.  The Consortium:

  • Identifies and prioritizes needed new NASGRO capabilities

  • Provides user support services

  • Provides a stable revenue stream to expand and accelerate NASGRO enhancements

  • Promotes technical interactions among fracture mechanics experts and practitioners
