Particle dynamics simulations of expansion of a cylindrical cavity within an infinite brittle medium [PDF]
Theoretical and Applied Mechanics, 2004 The present review focuses on the plane strain problem of high strain rate expansion of a cylindrical cavity within an infinite brittle material with random microstructure. The material is represented by an ensemble of "continuum particles" forming a two-

Earthquakes as dynamic fracture phenomena
Journal of Geophysical Research: Solid Earth, 2022 A large earthquake unlocks a fault-zone via dynamic rupture while releasing part of the elastic energy stored during the interseismic stage. As earthquakes occur at depth, the analyses of earthquake physics rely primarily on experimental observations and conceptual models.

Review of time-dependent fracture model of concrete
矿业科学学报, 2021 The integrity of concrete structures under strong earthquakes and the stability of concrete structures with cracks are concerns of national security strategies.These two issues are closely related to the time-dependent fracture behavior of concrete.The ...

Development and Application of Dynamic Fracture Plugging Test Device
Shiyou jixie, 2023 Due to the abnormal changes in formation pressure and wellbore pressure, the fracture morphology of stress sensitive fractured formations is complex and variable, and the problem of loss of drilling fluid is even more serious; in such a case, it is ...
