| style="text-align:left'" | '''''Objective:''' The primary objective of the Stress Intensity Factor (SIF) round robin was to evaluate differences between available SIF solutions for a single corner crack at a fastener hole with remote uniform tension loading. The evaluations included not only the root SIF solution but any corrections to account for single vs multiple cracks, finite width, and hole offset. These solutions were compared to explicit Finite Element Analysis (FEA) results of each case. Any findings were intended to drive improvements to solutions available to the fracture mechanics community.''

|'''''Objective:''' The purpose of this round robin exercise is to determine the variability of users, given the same loading spectrum, material data, and Initial Flaw Size (IFS) to predict the evolution of the crack front shape and the total life of a given geometry using the AFGROW framework as the life prediction tool. Certain aspects of the AFGROW framework will be provided for common use by each participant, and others will be left to the user's discretion. It is important that each participant follow this guidance so that variability in the predictions is limited to the aspects left to user discretion.''
