Effects of Residual Stress on Orientation Dependent Fatigue Crack Growth Rates in Additively Manufactured Stainless Steel

•The online crack compliance method was used for the first time on AM materials.•Consistent residual stress intensity factors (Kres) were found for each orientation.•DED material exhibited higher FCGRs when compared to wrought specimens.•Correcting for Kres brings FCGRs of DED and wrought material into agreement.•There is no significant orientation dependence of crack path in the AM material.
