Outline of Final Research Achievements

Macrostresses are evaluated from the measurement of matrix stress by X-rays using the stress-partitioning coefficient which can be determined experimentally or theoretically. In the measurement of residual macrostresses, the microstress due to mismatch of thermal expansion coefficient need to be subtracted from the measured value. A fracture mechanics parameter controlling the fatigue crack propagation behavior is the crack-tip opening range evaluated based on anisotropic elasticity. Prediction of fatigue crack becomes possible based on simultaneous measurement of stress and fiber orientation, combined with fracture mechanics approach.
