Shot peening for fatigue life improvement and forming of aerospace structures

The principle objective of this collaborative project is to develop in collaboration with the industrial partners novel methodologies for characterizing the shot peening and peen forming processes. One part of the program is devoted to establish analytical and numerical models for the prediction of the shot peening and peen forming processes. Experimental campaigns are planned in order to qualify the effect of the shot peening parameters on the peening results as well as to validate the developed models. The other part of the program is to assess the fatigue life improvement on the peened components. The crack initiation and propagation during cyclic loading in the peened component will experimental observed and numerically simulated in the microstructural scale.
