Connecting shear localization with the long-range correlated polarized stress fields in granular materials

Nature Communications, 2020
Understanding the behavior of jammed granular matter is important for a range of phenomena, from materials science to geology. Wang et al. uncover relations between stress correlations and emergence of localized shear bands due to external shear stress ...

Assessing the liquefaction potential of seabed soils based on ocean ambient noise in the Yellow River Delta

Frontiers in Marine Science, 2023
Seabed soils can undergo liquefaction under cyclic loading, resulting in a rapid decrease in strength and stiffness, which may lead to the destruction of offshore structures.

Back analysis of inter-ramp slope failure in Teghout copper mine [PDF]

International Journal of Mining and Geo-Engineering, 2018
Slope stability is one of the most important issues in open pit mining design. The main purpose of any open pit mine design is to propose an optimal excavation configuration, considering safety, ore recovery and financial return.

Granular Shear Flow in Varying Gravitational Environments [PDF]

Granular Matter (2013), Volume 15, Pages 129-137, 2013
Despite their very low surface gravities, asteroids exhibit a number of different geological processes involving granular matter. Understanding the response of this granular material subject to external forces in microgravity conditions is vital to the design of a successful asteroid sub-surface sampling mechanism, and in the interpretation of the ...
