Fatigue crack growth analysis software on Unipos website NASGRO Page has been added.

NASGRO Is a software developed jointly by the Southwest Research Institute and NASA for failure and Fatigue Crack Growth analysis of structural and mechanical parts. The most used computer program suite in the world for fracture mechanics and fatigue crack growth.

It also features a library of over 85 stress intensity factor solutions for cracks in various structures and materials, and a large library of material properties for approximately 500 metals.

NASGRO consists of integrated modules with the following functions.
・ Calculation of stress intensity factor
・ Calculation of crack growth life and critical crack size
・ Storing, acquiring, and curve fitting of fatigue crack growth and fracture toughness data
