... of geogrids has been determined through in-air uniaxial tensile tests conducted in various in-plane orientations. However, such tests do not adequately represent the stiffness under multi-axial in-plane loading conditions. To address this limitation, a novel multi-axial creep testing device has been developed...

... storage facilities ( TSF ), it is critical to quantify the degree of grain breakage and the induced creep and permeability reduction under sustained stresses over extended period of times. We conducted a 450-day long creep test on tailings sand retrieved from a currently active TSF at in situ vertical...

.... For this purpose, stability criteria for saturated viscous soils are extended to account for hydraulic state variables (e.g. suction and water content), which may provoke an unexpected increase of the creep rate. A simple one-dimensional constitutive law is used to test the proposed theory and assess its...

...C. Jia; J. Yu; J. Zuo; I. Eti-Inyenetrenchard Breccia lava is a comparatively weaken rock material that has been widely distributed in the Southwest China. Its creep behaviour and permeability evolution are significantly important to the long-term safety and stability of rock engineering...

...Q. Zhang; Y. Li; C. Wu; X. Fei; Y. Hong This study presents a systematic experimental investigation on the effects of joint roughness on the steady stage creep of rock joints. Multi-stage creep tests were conducted on synthetic rock joints with different roughness characterised by joint roughness...

... level or the wetting condition. Furthermore, creep is promoted after flooding and the secondary consolidation index increases essentially up to the same value obtained in initially saturated samples. These findings suggest that the effect of flooding on both primary and secondary compression can...

... constitutive model. This model is then validated against experimental results obtained from a series of laboratory multi-step creep tests. Denoting by G_s the Gibbs free energy of skeleton per unit volume and p_w the pore-water pressure, the inequality of Clausius–Duhem...

...) simulations of crushable aggregates. This paper incorporates the time-dependence of particle strength. A new equation is proposed and examined using DEM of 1D creep. The simulations show that while the plots may seem linear on a plot of voids ratio against the logarithm of time in the traditional way, the new...

...A. Ezaoui; F. Tatsuoka; A. Duttine; H. Di Benedetto It is shown that creep failure of geomaterials can be simulated by a non-linear three-component elasto-viscoplastic model. The model is described in the case of a single stress variable and the isotach viscous property type, although the model can...
