While bender elements have been widely used in clayey and sandy soils, recent studies have demonstrated their applicability in geotechnical engineering such as assessing stiffness characteristics of geogrid-reinforced aggregates during repeated load triaxial tests and in unbound aggregate layers under field ...
[36] reported (Fig. 1a) the typical deviator stress-shear strain data for unreinforced and reinforced specimens with different fibre concentrations under triaxial compression conditions. The initial stiffness of the composite soil was not influenced by the presence of the fibres and the increased ...
More recently, the model was refined to consider the intergranular strain of sand through an additional five model parameters (mR, mT, R, βr, \(\chi\)), which can account for the stress- and strain-dependent stiffness of sand at small strains. This model has been both well-documented ...
various literature surveys on liquefaction-induced devastation reveals five significant occurrences, namely the earthquakes in Niigata in 1964, Alaska in 1964, Kobe in 1995, Christchurch in 2011, and Sulawesi in 20181,2,3,4,5. Under the initial stress conditions, seismic waves generated during an...
conducting a series of triaxial compression tests. In current design practice, the stiffness and ultimate bearing capacity of a pile is evaluated by the following three methods: (i) use of stiffness and strength obtained from compression tests on undisturbed samples, (ii) use of the results of ...
Through an eigenvalue analysis, two modes of instability arenidentified at the local contact level: the singularity of tangential stiffness matrix and the loss of positiveness of second-order work. Thenconstitutive model is applied to simulate drained and undrained triaxial tests on Toyoura sand of...
