Fracture process zone (FPZ) in quasi-brittle materials: Review and new insights from flawed granite subjected to uniaxial stress
JZ Zhang, XP Zhou - Engineering Fracture Mechanics, 2022 - Elsevier
In the failure of quasi-brittle materials such as rocks, microstuctural damage always
precedes macroscopic fracture and manifests itself in the formation of fracture process zones …
