Cohesive Zone Model
The cohesive zone model implies that normal stress continues to be transferred across a discontinuity which may or may not be visible as shown in Fig. 6.1. This stress is determined from the softening stress–strain relation that various rocks exhibit in calibrations tests. This transferred normal stress is a function of the separation and ...
