抜粋

Residual stresses induced by cooling down from the elaboration process in SiC/Ti-15-3 composite were calculated by the finite element model using MARC and MENTAT software. An analytical model (derived from those of Eshelby and of Mikata and Taya) already used for ceramic matrix composites has also been used in this study for elementary composites. The influence of uncertainty on thermomechanical properties and also the influence of fibre packing and spacing were also studied. Then, evolution (relaxation) of the thermal residual stresses (TRS) during a fatigue test were investigated. Results show that the TRS decreased rapidly during the first cycles and then became almost constant at about one-third of their initial values.
