Abstract: Medium-to-dense sand sheared under undrained or essentially undrained conditions shows a dilative hardening response when the stress crosses a phase transformation state and gets into the dilative zone. When the stress ...

Abstract: “Ground response” in geotechnical earthquake engineering refers to the response of level ground subjected to seismic loading originating from the underlying rock formation. Catering to this special loading condition, the ...

Abstract: The steady-state line relates the effective confining pressure (

Abstract: This paper discusses the state-dependent strength of sands from the perspective of unified modeling in triaxial stress space. The modeling accounts for the dependence of dilatancy on the material internal state during the ...

Abstract: This paper describes an experimental program aimed at a close examination of the dynamic properties (shear modulus and damping ratio) of a normally consolidated dry sand as affected by the previous vibration. Tests were ...

Abstract: This study presents direct evidence for the influence of the previbration cycles induced in the conventional resonant column tests on the measured dynamic properties of a dry sand. The tests were performed on an energy-injecting ...

Abstract: The extent of flow deformation in an embankment dam is determined by the driving forces and the residual strength of the soil, as well as by the kinematic constraints. The soil conditions of berm and buttress, as well as ...

Abstract: This paper presents a state-dependent constitutive model for sand formulated within the critical-state framework and its implementation into a numerical analysis (FLAC3D) program. The implemented model was verified by using ...

Abstract: The coaxial and totally noncoaxial parts of a tensor in regard to another reference tensor are derived in closed analytical form based on representation theorems of tensor-valued isotropic functions. In the process a new ...
