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: 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: 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 ...
