SwRI Software

NASGRO is a suite of fracture mechanics and fatigue crack growth analysis computer programs that perform assessments of structural life, compute stress intensity factors, and process and store fatigue crack growth properties. Working closely with NASA and industry, SwRI releases new versions of NASGRO annually with many new features. Recent enhancements include many new K solutions, residual stress capabilities, increased speed, new GUIs, residual strength diagrams, spectrum editing, temperature effects, cyclic shakedown models, cycle counting algorithms, and a revised material database. NASGRO received an R&D 100 Award in 2003 and the NASA Software of the Year award in 2003.
