	\|'''Objective:''' IRAD stands for "Internal Research and Development" which is a mechanism used by QinetiQ to fund research projects. In this case, we have completed a major project including testing and analytical model development. The project aim was to account for an observed behaviour for modelling of fatigue crack growth where the analysis results consistently under predict the test life. This was evident in the DST ASSIST Challenge presented at the ASIP Conference in 2020. The project here considered three materials; 2024-T3, 7075-T6 and 7075-T7351. Testing was performed on Middle Tension (M(T)) specimens under conditions of Constant Amplitude loading in the constraint-loss regime, with and without spike overloads, and also under representative spectrum loading. The project scope is detailed in the ~~attached documents.
