Layton, Utah 84041

The next AFGROW Workshop will be held at Davis Conference Center in Layton, UT on September 12-13, 2023.

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.

The Davis Conference Center is close to the Hill AFB South Gate, and is conveniently close to several hotels in Clearfield and Layton. Continental breakfast and afternoon refreshments will be provided.

You can register for the User Workshop online or alternatively you can download the registration form and fax or email it to us.

Fracture Analyses of Thin-Ductile Aerospace Materials
J. C. Newman - Fatigue & Fracture Associates, LLC

The critical crack-tip-opening angle or displacement (CTOA/CTOD) fracture criterion is one of the oldest fracture criteria applied to metallic materials. Improved computer-aided photographic methods have been developed to measure CTOA during the fracture process; and elastic-plastic, finite-element analyses (ZIP2D) with a constant CTOA and a plane-strain core have been used to simulate fracture of laboratory specimens. The fracture criterion has been able to link the fracture of laboratory specimens to structural applications. This paper analyzes fracture of cracked thin-sheet 2219 aluminum alloy over an extremely wide range in width, crack-length-to-width ratio, and applied loading (tension, bending, and combined tension-bending loads). The results from the critical CTOA fracture analyses on the thin-sheet material showed that the stress-intensity factor at failure (KIe) was linearly related to the net-section stress (Sn), as predicted by the Two-Parameter Fracture Criterion (TPFC).
