Abstract: A comprehensive constitutive model has been formulated to capture the complex behaviors of gravelly soils under irregular cyclic loading. The application of this model aims to analyze the nonlinear deformation behavior of ...

Abstract: In this study, cyclic triaxial tests were performed on Zipingpu gravel, and they were followed by a discrete element study that was designed to investigate the stress-dilatancy relationship of gravelly soils under cyclic ...

Abstract: This paper proposes sliding mode control of vibration in three types of single-degree-of-freedom (SDOF) fractional oscillators: the Kelvin–Voigt type, the modified Kelvin–Voigt type, and the Duffing type. The dynamical ...

Abstract: This paper addresses the Lyapunov functions and sliding mode control design for two degrees-of-freedom (2DOF) and multidegrees-of-freedom (MDOF) fractional oscillators. First, differential equations of motion for 2DOF ...

Abstract: In this study, cyclic triaxial tests were performed on Zipingpu gravel, and they were followed by a discrete element study that was designed to investigate the stress-dilatancy relationship of gravelly soils under cyclic ...

Abstract: Fractional calculus is viewed as a novel and powerful tool to describe the stress and strain relations in viscoelastic materials. Consequently, the motions of engineering structures incorporated with viscoelastic dampers ...

Abstract: One of the most important features of soil behavior is the dependence of stress path. A series of large-scale triaxial compression tests was conducted to investigate the effect of stress path on critical state and particle ...

Abstract: The collapse settlement induced by wetting deformation during the impounding period has a significant impact on the safety of rockfill dams. Previous large-scale triaxial wetting investigations on rockfill have predominantly ...
