Cohesive Zone Modeling of Grain Boundary Micro-cracking …

Bilinear cohesive zone models have been adopted for simulating impact damage in brittle materials (e.g., Zavattieri and Espinosa, 2001; Kandula et al., 2005). The bilinear cohesive zone model allows the user to control the initial slope of the trac-tion–displacement curve, and thus restrict the effect of the artificial compliance (Geu-
