Abelev, Andrei V., Auteur ; Victor N. Kaliakin, Éditeur scientifique ; Poul V. Lade, Auteur |Drained true triaxial tests on dense Santa Monica Beach sand deposited with a cross-anisotropic fabric have been performed to study the failure condition in the principal stress space. The failure surface was assumed to be symmetric around the v[...]

Jerry A. Yamamuro, Auteur ; Antonio E. Abrantes, Auteur ; Poul V. Lade, Auteur |Drained triaxial compression tests on crushed coral sand were performed from near-static strain rates to very high strain rates (up to approximately 1,800%/s). Experiments were performed on dry, vacuum-confined axisymmetric specimens at two diff[...]

Poul V. Lade, Auteur ; Jungman Nam, Auteur ; Carl D. Liggio Jr., Auteur |Stress relaxation and stress drop-relaxation tests have been performed to complement a test series performed to study strain rate, creep, and stress drop-creep effects on crushed coral sand. Drained experiments with constant effective confining [...]

Poul V. Lade, Auteur |Experimental evidence and analyses of results of three-dimensional (3D) tests show that the shape of the failure surface for soils is influenced by the intermediate principal stress, shear banding, and cross anisotropy. Presented here is a formu[...]

Abelev, Andrei V., Auteur ; Suresh K. Gutta, Auteur ; Poul V. Lade, Auteur |A constitutive model has been developed to capture the behavior of cross-anisotropic frictional materials. The elastoplastic, single hardening model for isotropic materials serves as the basic framework. Based on the experimental results of cros[...]

Poul V. Lade, Auteur ; Carl D. Liggio Jr., Auteur ; Jungman Nam, Auteur |The part of sand behavior that is affected by time, such as creep, relaxation, and loading rate effects are not similar to those observed for clay. To throw more light on the time effects in sand, many series of drained triaxial compression expe[...]

Hamid Karimpour, Auteur ; Poul V. Lade, Auteur |Based on previously obtained experimental results, a mechanistic picture of time effects in granular materials is presented. Accordingly, time effects are caused by grain crushing, which in turn is time dependent, as indicated by static fatigue [...]
