Full-Scale Shake Table Cyclic Simple Shear Testing of Liquefiable Soil
… research works towards comparing large-scale simple-shear liquefaction testing to small-scale simple-shear liquefaction testing of a #2/16 Monterey sand specimen. The bucket top was modified in order to apply a vertical load to the soil skeleton to replicate overburden soil conditions. Access …

Experimentally validated DEM modelling of granular materials under simple shear testing
Simple shear testing’s ability in simulating realistic in situ conditions makes it an effective element-level testing method to study the response of granular materials under uni-directional and multi-directional loading. DEM modelling provides complementary information such as contact networks and …

Direct shear and direct simple shear tests: a comparative study of the strength parameters and their dependence on moisture and fines contents
Shear strength of soil is characterized by cohesion, angle of internal friction and dilatation. The first two parameters mentioned primarily define the soil's ability to resist shear stress underspecified load. These parameters can be determined by tests conducted either in the laboratory or the …
