Aging effects on liquefaction resistance of sand estimated from laboratory investigation
Soils and Foundations, 2023 Liquefaction resistance is known to increase concomitantly with the increase in time after construction or sedimentation. Nevertheless, the mechanisms of its aging effect on liquefaction have not been completely elucidated.

Evaluation of local damping effect on static and dynamic behaviors of granular materials using DEM modeling [PDF]
مهندسی عمران شریف, 2022 Frictional sliding may not be sufficient for the stability of a system. In almost all models in the Discrete Element Method (DEM), a local non-viscous damping is used to balance the system by applying a damping force with a magnitude proportional to the ...

Influence of Load Frequency on Cohesive Soil Respond
Geosciences, 2018 The mechanism of cohesive soils response to cycling loading is less investigated compared to cohesionless soils. Multiple load-unload cycles cause significant changes in the structure of cohesive soils, which result in complex behaviour under the given ...
