AFGROW User Workshop 2025

Hilton Garden Inn Hilton Garden Inn
2271 S Washington Blvd
Ogden Utah 84401

The next AFGROW Workshop will be held at the recently renovated Hilton Garden Inn in Ogden, UT on September 9-10, 2025.

Are you, or someone you know, interested in learning about the latest developments happening right now in Fracture Mechanics? Would you like the chance to meet a wide range of experts from across the industry? Do you want to know more about the uses and capabilities of Crack Growth Analysis tools? All of these opportunities and more are available to you at the AFGROW Users Workshop.

The purpose of the Workshop is to provide a forum for AFGROW Users to come together to exchange information and best-practices, network with peers from the industry, and get a chance to talk with the AFGROW developers and community.

Group discussions will also provide direction for new capabilities and improvements, best practice methods, and tips and tricks from the experts. The AFGROW team will also provide information on our latest development efforts for the upcoming year.

Who should attend: Engineers, researchers, technologists, managers who are users of AFGROW, and/or anyone that has an interest in Crack Growth Analysis tools.

Venue: The Hilton Garden Inn in Ogden, UT, within walking distance of more than a dozen restaurants. Complimentary parking is available for guests. Continental breakfast and afternoon refreshments will be provided.

Online Hotel Reservations: Special group rate of $185.00 until August 8, 2025.

State-of-the-Art Risk Assessment with SMART|DT plus AFGROW Integration
Nathan Crosby - AeroMatter

The integration of SMART|DT with AFGROW enables more advanced and detailed risk assessments that were previously too computationally expensive to perform. With the addition of an AFGROW interface, SMART|DT can now perform crack growth analyses coordinated with its unique capabilities—such as adaptive importance sampling, generation of crack growth spectra from mixed usage profiles, and inspection schedule optimization. This presentation will focus on how the capabilities of AFGROW and SMART|DT can be used complementarily and explore the possibilities now available that are beyond deterministic crack growth based probabilistic damage tolerance analysis.

This work is the result of a very successful integration of AFGROW with SMART|DT that we are excited to share with the AFGROW user community.

Enhancing Residual Stress Backwards-Calculation: A Convex Optimization Approach for Rapid and Reliable Solutions
Ian Hokaj - USAF, A-10 ASIP Analysis Group

Accurate determination of residual stress fields is critical for reliable fracture mechanics predictions. This presentation introduces a new, automated method for back-calculating residual stresses from marker band data, using StressCheck to compute stress intensity factors and BAMpF to validate results. By reformulating the inverse problem as a convex optimization, a unique and globally optimal solution can be obtained efficiently. The resulting algorithm achieves sub-second solve times, drastically reducing the analysis time compared to traditional, iterative methods. Results from several datasets demonstrate realistic stress field shape and excellent correlation with experimental crack growth data, validating the accuracy and efficiency of this approach for approximating residual stresses in metals.
