Fatigue Life Modeling at CX and Interference Holes (from ERSI Workshop 2019)
Abstract: Continuation of previous year’s work by AP/ES and ESRD on crack closure. Additionally, a task evolved from USAF goals dictated at ERSI 2018 to study the residual stress redistribution at interference filled holes. The goal of this new task was to better understand interference fit fasteners and their interaction with residual stresses from cold-working (CX).
Originally presented at the Engineered Residual Stress Implementation (ERSI) Workshop 2019 in Clearfield, UT.
