Long-Term Cyclic Triaxial Tests With Dem Simulations [PDF]
PARTICLES 2017, V International Conference on Particle-based Methods – Fundamentals and Applications, 2017 The present paper presents the capability of Discrete Element Method (DEM) to simulate a long-term cyclic drained triaxial test (up to 100,000 cycles). The results regard the progressive accumulation of plastic strain as function of the number of particles and the initial particles rearrangement.

Application and comparison of multistage triaxial compression test procedures on reconstituted Ankara clay [PDF]
E3S Web of ConferencesThe ability to conduct conventional triaxial compression tests on multiple identical specimens is restricted by available sample quantity, sample homogeneity, as well as testing duration.

Liquefaction Characteristics of Sand With Polypropylene Fiber at Low Confining Stress
Frontiers in Built Environment, 2020 The present study evaluates the liquefaction characteristics of Ottawa sand with polypropylene fiber using cyclic triaxial test. A series of stress-controlled cyclic triaxial tests were performed at 34.47 kPa (5 psi) effective confining pressure ...

Modelling the monotonic and cyclic behaviour of sands using Artificial Neural Networks [PDF]
EPJ Web of Conferences, 2021 In this study artificial neural networks (ANN) are used to simulate the monotonic and cyclic behaviour of sands observed in laboratory tests on Karlsruhe sand under drained and undrained conditions.

Soil liquefaction as an identification test [PDF]
E3S Web of Conferences, 2019 Time-consuming and complicated investigations of soil liquefaction in cyclic triaxial tests are the most common way of laboratory analysis of this phenomenon.

A simple method for the determination of sensitivity to density changes in sand liquefaction
Open Geomechanics, 2021 Fully saturated loose coarse-grained soils are known to be prone to liquefaction. Conventional laboratory tests for soil liquefaction include usually cyclic testing in triaxial apparatus.

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 ...

Geofluids, 2021 Sand elements in the natural or manmade field have often undergone initial static shear stresses before suffering cyclic loading. To explore the effect of static shear stress, a series of undrained cyclic triaxial tests were performed on dense and loose ...

Undrained response of Sydney sand under non-reversal cyclic loading [PDF]
E3S Web of Conferences, 2019 Stress history and loading path can significantly influence the cyclic response of sands. It is well known that cyclic behaviour under non-symmetrical cycling is generally different from that under symmetrical loading around zero deviator stress ...

Damping Ratio of Sand Containing Fine Particles in Cyclic Triaxial Liquefaction Tests
Applied Sciences, 2023 Sand liquefaction triggered by earthquakes is a devastating geological disaster and has emerged as an engaging topic in earthquake engineering. With an enhanced understanding of pure sand liquefaction promoted by laboratory research, there is a growing ...
