13th International Conference on Fracture June 16–21, 2013, Beijing, China -6- microcracking of the matrix. The microcracking of the matrix then propagated toward the edge of the specimen and induced final failure of the specimen. It is found that the prediction of the initiation and progression of the damage is in good agreement with experimental results. In conclusion, we demonstrated that several SENT specimens of self-healing FRP exhibited damage progression along the coated fiber strands and achieved successful healing. Moreover, the numerical and experimental results showed similar trends. References [1] K. Sanada, I. Yasuda, Y.
