What is AFGROW?
AFGROW was originally developed as an Air Force fatigue crack growth life analysis tool by the U.S. Air Force Research Laboratory at Wright-Patterson AFB, OH. The history of AFGROW can be traced back to ASDGRO, a program developed by Mr. Ed Davidson at the Air Force Aeronautical Systems Division in early to mid 1980's. A full history of AFGROW can be found on the AFGROW 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 a structure fails.
Who develops AFGROW?
AFGROW is under development as a commercial product by LexTech, Inc.
How much does AFGROW cost?
The current commercial version of AFGROW (Version 5.2) is available to purchase at a cost of $995.00 (US). This price includes one hour of technical support and access to the “MyAFGROW” section of the AFGROW web site for a period of one-year after a license has been activated. Access to the MyAFGROW section of the web site includes the ability to search/download information from our fracture mechanics database.
Do you offer network licensing?
We offer three licensing options. The most common option is a node locked license where AFGROW may be used on a single PC or laptop. We offer a dongle based license that uses a removable USB “dongle” to verify the license. AFGROW may be loaded on more than one PC or laptop, but the dongle must be installed to use the license. The dongle is purchased separately through LexTech, Inc. Finally, the network licensing option is available to customers who purchase 15 licenses or more.
What kind of support do you offer?
Context sensitive html help is included with AFGROW to provide information on how various AFGROW features and capabilities may be used. In addition, a large number of references, including a comprehensive Users Guide and Technical Manual is available on the My AFGROW page section for users who have a registered account on the AFGROW Web Site. Technical support for the commercial release is available through LexTech, Inc. One hour of support is provided as part of the purchase of an AFGROW license for one year after the license is activated. One hour of support is also provided as part of the annual maintenance option. Additional support is available through LexTech, Inc.
Can AFGROW users make suggestions for new features and capabilities?
Yes. The developers of AFGROW are proud to have such an active user base and welcome all
comments and suggestions.
We are also very happy to add new features and capabilities, and will work with governments, industry, and individuals to implement them. However, AFGROW is not open source and the source code is not available to the public.
Why is AFGROW no longer free?
The Air Force Research Laboratory has discontinued funding for new development, maintenance, and training. All funding for these services must now be provided by AFGROW Users.
How Can I purchase the commercial version of AFGROW?
Users must register on this site to obtain a login ID and Password. Once approved, users may login at any time for access to the My AFGROW section of the web site.
