  Investigation on Open Loop Position Control of Amplified Piezoactuator

  By Veeresha R K, Astron Manoj Tauro, Muralidhara ., Rathnamala Rao

  Abstract: Amplified piezoelectric actuators (APAs) consist of stacked piezoelectric actuators inside a flexural mechanical amplifier which helps in amplifying the displacements of the piezostacks in static and dynamic conditions. Accounting for their precision movement and dynamic characteristics, these actuators are extensively used in micropositioning, active damping, and microactuation applications. In this paper, FEM analysis of mechanical flexural amplifier of APA230L piezoactuator was performed to estimate its stiffness in the horizontal direction …

  Assessment of Liquefaction Potential Index for Sylhet City considering Maximum and Average Amplification Factor

  By Md. J. B. Alam, Shriful Islam, Nur M. R. Hoque, Shilpy R. Basak, A. I. Shuvo, S. K. Das

  Abstract: Soil liquefaction often occurs in saturated or partially saturated silty or sandy soil when an earthquake generates dynamic cyclic stress in the soil mass, reducing shear strength and stiffness. This study aims to assess the seismic soil liquefaction hazard potential for Sylhet City using shear wave velocity profiles of 49 boreholes. Factor of Safety (FOS) was evaluated taking into account shear wave velocity and maximum intensity of surface acceleration corresponding …
