What is AFGROW?
AFGROW was originally developed as the Air Force fatigue crack growth life analysis tool. The history of AFGROW can be traced back to ASDGRO, a program developed by Mr. Ed Davidson in early to mid 1980's. A full history of AFGROW can be found on the history page. Simply put, AFGROW is a program that "predicts" the life of a metallic structure subject to repeated fatigue loading. This prediction is used to establish an inspection schedule so that cracks may be found before the structure fails.
