In his note, Forrest compares the results of an experimental investigation of the notched fatigue strength of HE 15 aluminium alloy (L.64/L.65 type) in three conditions of heat treatment with predicted values obtained using the analysis by Gunn. This analysis appears in R.Ae.S. Fatigue Data Sheets A.00.01 and .02.
The analysis requires a minimum knowledge of four parameters, Kt’ the elastic stress concentration factor, ft the tensile strength, ƒp the 0·1 per cent proof stress and Sao the fatigue strength under reversed loading for the specified endurance Ncycles.
