The results show that brittle fracture occurs in matrix and the P-WCMOD(crack mouth openingdisplacement) curve is linear till loading to failure.

For crack-openingdisplacement tests, a specimen is notched and then fatigued by flexing to obtain a fine crack. Force is then applied until the crack begins to grow.
