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.

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 ...

On-sample water content measurement for a complete local monitoring in triaxial testing of unsaturated soils [PDF]
, 2012 To provide a complete local monitoring of the state of an unsaturated soil sample during triaxial testing, a local water content measurement device was adapted to a triaxial device comprising the measurement of local displacements (Hall effect ...

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.

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 ...
