The authors have been developing the constitutive model for a single crack in concrete and making experimental identification of the four basic coefficients.
In the present paper, the nonlinear behavior characterizing the crack surface is discussed on the basis of numerical results calculated from the authors' proposed constitutive model. Moreover, comparison to Bazant·Gambarova's model is made, and pathdependency and Coulomb's friction law being compared with rock joints are examined. It is found that numerical simulation may be a useful tool to quantitatively analyze the characteristics of cracked concrete, being comparable to experimental studies.
