Fracture process zone (FPZ) is formed in crack tip due to inhomogeneity of concrete. The fracture behavior of concrete in FPZ remains unclear. In this study, to reproduce the fracture behavior in FPZ, we analyze crack propagation and crack formation using the method of analysis considering formation, coupling, open and close of micro-crack in microscopic structure model made from picture of real concrete. Because we can't measure fracture energy and tensile strength in microscopic structure, we change them in the numerical analysis. We compare the simulation result with the experiment result by existing article. As a result, we conclude that the result of simulation has the possibility of reproducing fracture behavior in FPZ.
