Thermal Residual Stresses (TRS) induced by cooling down from elaboration process in SiC/ Ti-15-3 composite are evaluated using several models (present in part I). Influence of thermomechanical properties is investigated. It is shown that a small uncertainly on coefficient of thermal expansion has a huge influence on TRS. It is also highlight that the analytical model proposed is a suitable model to obtain quickly information about TRS (rather than the finite element analysis which is a little more accurate but longer too). Then evolution (relaxation) of the TRS during a fatigue test are investigated. Results show that the TRS decrease rapidly during the first cycles and then become almost constant at about one third of their initial values.
