2022 Interference Fit Fastener Round Robin

Point of Contact(s): Robert Pilarczyk

Objective: The primary objective is to establish a set of reference stress analyses agreed upon by the working group, as well as establish the baselines stress state that can be utilized for follow-up phases. Additionally, the analyses can be utilized to characterize: 1.      The onset of plastic deformation and the bounds of elastic vs. plastic regimes 2.      The relationship between far field loading and local strain cycles 3.      The stress state dependency as a function of key factors (e.g. interference level, modeling assumptions, remote loading)
