Seepage and deformation characteristics of sliding-zone soils under cyclic seepage pressure

Journal of Rock Mechanics and Geotechnical Engineering
Numerous incidents and failures of landslides in reservoir areas are attributed to water level fluctuations, which frequently induce cyclic changes in seepage pressure within the soil masses.

CFD modelling of two-phase stirred bioreaction systems by segregated solution of the Euler–Euler model [PDF]

, 2013
An advanced study of a bioreactor system involving a Navier–Stokes based model has been accomplished. The model allows a more realistic impeller induced flow image to be combined with the Monod bioreaction kinetics reported previously. The time-course of

Experimental study on development patterns of volumetric strain and predictive modeling for saturated coral sands

Yantu gongcheng xuebao
The coral sand has better drainage conditions, and the drainage deformation of the saturated coral sand under earthquake and wave loads can easily cause damage to the seabed and nearby structures.

Memory of the Unjamming Transition during Cyclic Tiltings of a Granular Pile [PDF]

, 2005
Discrete numerical simulations are performed to study the evolution of the micro-structure and the response of a granular packing during successive loading-unloading cycles, consisting of quasi-static rotations in the gravity field between opposite ...

Deformation and failure characteristics of weathered granite under uniaxial compression

AIP Advances, 2019
In this paper, we have examined the crack formation of weathered granite by monitoring acoustic emissions (AE) under uniaxial compression. Except for the uniaxial compressive strength (UCS), the thresholds have been determined for crack closure, crack ...

On the Lightweight Potential of Laser Additive Manufactured NiTi Triply Periodic Minimal Sheet Lattices

Advanced Engineering Materials, EarlyView.
This study explores the lightweight potential of laser additive‐manufactured NiTi triply periodic minimal surface sheet lattices. It systematically investigates the effects of relative density and unit cell size on surface quality, deformation recovery, compression behavior, and energy absorption.

Dynamic deformation characteristics of saturated coral sand incorporating fines content under drained conditions

Case Studies in Construction Materials
The effect of the fine content (FC) and the relative density (Dr) on the deformation properties of saturated coral sand has been explored through a series of drained cyclic triaxial tests.

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing
