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 ...

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 ...

Dilatancy relation for overconsolidated clay [PDF]
, 2017 A distinct feature of overconsolidated (OC) clays is that their dilatancy behavior is dependent on the degree of overconsolidation. Typically, a heavily OC clay shows volume expansion, whereas a lightly OC clay exhibits volume contraction when subjected ...

Long-Term Cyclic Triaxial Tests With Dem Simulations
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.
