Investigating the Dynamic Behavior of Gabbro Specimens With Echelon Joints

Energy Science &Engineering, Volume 13, Issue 7, Page 3620-3630, July 2025.
Investigating the dynamic behavior of rock specimens with echelon joints based on SHPB tests. ABSTRACT To reveal the influence of dynamic load on the dynamic damage behavior of jointed rock masses, split Hopkinson pressure bar (SHPB) system was employed to test platy gabbro samples with joint angles of 15°, 30°, 45°, 65°, and 75° at an impact pressure ...

Study on Compound Percussive Drilling: Rock‐Breaking Mechanism of High Confining Pressure Formation in the East China Sea

Energy Science &Engineering, Volume 13, Issue 7, Page 3688-3703, July 2025.
ABSTRACT The effect of improving the depth of penetration (ROP) in deep, high‐confining pressure formation is closely related to the rock‐breaking method, which has become a bottleneck restricting the efficient development of oil and gas. Based on the current engineering practice of the Xihu block in the East China Sea Basin, experimental research on ...

Fracturing behaviors of flawed granite induced by dynamic loadings: A study based on DIP and PFC

Deep Underground Science and Engineering, Volume 4, Issue 2, Page 290-304, June 2025.
This research examines granite's mechanical properties under split‐Hopkinson pressure bar testing, focusing on factors such as grain size and flaw dimensions. The study reveals that tension cracks are prevalent across grain sizes, with most intergrain cracks occurring between feldspar and quartz.
