In this research, the composite material with shape memory function is used as model material of photoelastic experiment. Photoelastic experimental hybrid method is developed in this research, it is assured that it is useful on the obtaining stress intensity factor and the separation of stress components from only isochromatic data. The measuring method of stress intensity factor of intelligent material by photoelastic experiment is introduced. As the result, the fracture resistance of the matrix (base material) as well as the TiNi fiber improved. This is due to decreasing stress intensity factor K_I caused by raising the ambient temperature in the iso-temperature furnace.
