Objective: A series of wide plate panel tests were designed by DST and tested in support of a recent full-scale fatigue test program. This Military Transport Aircraft Crack Growth Prediction Challenge was aimed at predicting the crack growth life commencing from a nominal initiating length to final failure, utilizing notched test specimens containing existing pre-cracks. Participants provided DST with details of their analysis inputs and assumptions and crack growth versus spectrum block predictions (including crack growth rate and final failure length prediction). Where possible details regarding tools and methods used for crack growth and spectrum manipulation were also encouraged to be shared.
