Nonlocal Criteria for Brittle and Quasi-Brittle Fracture of Geomaterials and Rocks
E3S Web of Conferences, 2018 Nonlocal criteria are used for prediction materials and rock mass failure near stress concentrations (pores, faults, openings, excavations). A common property of nonlocal fracture criteria is the introduction of the intrinsic material length ...

Grouting mechanism in fractured rock considering slurry-rock stress coupling effects
Yantu gongcheng xuebao, 2018 The slurry-rock stress coupling effects have a great influence on the grouting process in fractured rock. In order to describe the dynamic grouting process, a piecewise equation is used to govern the deformation process of rock fissure, and a theoretical

Advanced Engineering Materials, EarlyView.Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

Identifying the real fracture hidden in rock microcrack zone by acoustic emission energy
International Journal of Mining Science and TechnologyIdentifying the real fracture of rock hidden in acoustic emission (AE) source clusters (AE-depicted microcrack zone) remains challenging and crucial. Here we revealed the AE energy (representing dissipated energy) distribution rule in the rock microcrack
