Table 1.

Cohesive model parameters used in the simulations based on experimental data in the literature (Brown et al., 2000; Cezayirlioglu et al., 1985; McCalden et al., 1993; Zioupos and Currey, 1998). Note that σ_nc, σ_sc (=σ_tc), G_nc, and G_sc (=G_tc) are the normal strength, the shear strength, the critical energy release rate for opening mode, and the critical energy release rate for shear mode, respectively.
