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.

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 ...

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
