Experimental Study on Seismic Compression of Chinese Loess under Cyclic Direct Simple Shear Testing
Advances in Civil Engineering, 2022 Seismic compression is the accumulation of contractive volumetric strains in unsaturated soil from earthquake shaking. For Chinese loess, the behavior of seismic compression is extremely significant and has been recognized in historical earthquakes. As a

Liquefaction Characteristics of Sands Based on Cyclic Direct Simple Shear Test [PDF]
Journal of the Korean Society of Hazard Mitigation, 2020 In this study, a series of cyclic direct simple shear tests were conducted on Pohang sand, Jumunjin sand, and Ottawa sand. The cyclic resistance ratio (CRR) was derived on the basis of the test results obtained. For verification of the effect of particle distribution on liquefaction resistance, the simplified method for evaluation of the possibility of

A semi-empirical model to predict excess pore pressure generation in partially saturated sand [PDF]
E3S Web of Conferences, 2020 Past studies revealed that excess pore pressure generation due to cyclic loading is highly governed by induced strains, volumetric deformation potential of soil, number of cycles, and bulk stiffness of pore fluid.

Changing Soil Response During Episodic Cyclic Loading in Direct Simple Shear Tests
International Journal of Offshore and Polar Engineering, 2023 Undrained cyclic loading of normally consolidated clays, interspersed with consolidation (i.e., episodic cyclic loading), hasbeen shown to lead to softening followed by hardening, manifested by evolving parameters such as strength, stiffness, andcoefficient of consolidation.

Behaviour of a loose silty sand under static and cyclic loading conditions [PDF]
E3S Web of Conferences, 2019 In recent years, considerable progress have been made in the study of liquefaction and flow failures with the introduction of the notion of steady-state of deformation and “collapse” envelope.

Macro–Meso Mechanical Behavior of Loose Sand under Multi-Directional Cyclic Simple Shear Tests
Applied Sciences, 2023 Loose sand samples under different complex shear paths and directions of consolidation shear stress were simulated using bi-directional simple shear DEM models. Liquefaction characteristics and corresponding meso-mechanisms were analyzed, and the following conclusions were drawn.

Geotechnical Testing Journal, 2020 Abstract A series of undrained cyclic direct simple shear (CDSS) tests on dense Toyoura sand has been performed with the aim to investigate the influence of the stiffness of the DSS device on test results. To this end, springs were installed to reduce deliberately the stiffness of the apparatus.
