![]() ![]() the arrangement of displacement sensors in ice fracture experiments (Dempsey et al. The size of this zone is needed in experiments for measuring purposes, e.g. In cohesive zone theory, the fully developed process zone (FDPZ) is the region in which material degradation is activated. ![]() Further, for this setup, the CEM-based numerical model captures the size effect and can be used to extrapolate small-scale test results to full-scale. Maximum cohesive zone sizes are given for rectangular and linear softening. The (FDPZ) size for finite plates is influenced by the cracked plate size and physical crack length. After successful validation, the FDPZ size of finite plates is calculated with the same numerical scheme. It is validated against existing analytical solutions. A numerical CEM-based model is built to compute the FDPZ size for an edge crack in a finite square plate of different lengths spanning several magnitudes. With respect to fracture testing, the CEM is also a potential tool to extrapolate laboratory test results to full-scale while considering the size effect. Analytical solutions for the exact FDPZ size only exist for highly idealised bodies, e.g. However, the FDPZ size is generally not known beforehand. The size of the fully developed process zone (FDPZ) is needed for the arrangement of displacement sensors in fracture experiments and choosing element size in numerical models using the cohesive element method (CEM). ![]()
