Micromechanics of Fatigue.

Abstract

In this final report, the results given in the first two annual reports are recalled. Application of the derived tools to Apha-Two-Titanium Aluminide Alloy is made with a first series of strain controlled fatigue tests the locally coupled model is first identified and then checked on a second series of stress controlled fatigue tests. The good agreement allows to use this locally coupled method to predict fatigue crack initiation on brittle or quasibrittle materials.
