WebJul 1, 2024 · In cohesive zone theory, the fully developed process zone (FDPZ) is the region in which material degradation is activated. The size of this zone is needed in experiments for measuring purposes, e.g. the arrangement of displacement sensors in ice fracture experiments (Dempsey et al. 1999a, b, 2004; Lu et al. 2015a, 2024), and in … Web1 day ago · During the cutting simulation process of the following five groups, when the cutting depth exceeds 1 mm, in Fig. 14, the proportion of Type I failure gradually decreases. Among them, three groups of simulated cohesive elements are mainly shear failure, and the granite gradually shows the trend of brittle failure.
