RISAn Iterative-Based Feedforward-Feedback Control Approach to High-Speed Atomic Force Microscope Imaging
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article presents an iterative-based feedforward-feedback control approach to achieve high-speed atomic force microscope (AFM) imaging. AFM-imaging requires precision positioning of the probe ...
Unified Strength Model Based on Hoek-Brown Failure Criterion for Circular and Square Concrete Columns Confined by FRP
Publisher: American Society of Civil Engineers
Abstract: Most existing models for evaluating the strength of fiber-reinforced polymer (FRP)-confined concrete columns are based in an early work. In this paper, a new model based on the Hoek-Brown failure criterion is proposed. The ...
Finite Element Method Simulations to Study Factors Affecting Buried Pipeline Subjected to Debris Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As the debris flow caused by sustained rainfall would cause destructive damage to buried pipeline, the safety of buried pipeline under impact of debris flow draws increasing attention. This paper focuses on the mechanical ...
Modeling and Identification of Hysteresis in Piezoelectric Actuators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a model and the associated identification procedure are proposed to precisely portray the hysteresis behavior in piezoelectric actuators. The model consists of basic physical ...
Spherical and Aspheric Microlenses Fabricated by Excimer Laser LIGA-like Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an effective and low-cost method for fabricating spherical and aspheric microlenses based on excimer laser LIGA-like processes. It is based on a newly developed excimer laser ...
Improved Displacement-Based Timoshenko Beam Element with Enhanced Strains
Publisher: ASCE
Abstract: This paper presents an enhanced strain formulation for conventional displacement-based (DB) Timoshenko beam elements accounting for shear deformations. The proposed beam element is an extension of the original enhanced ...
Surface Roughness and Reynolds Number Effects on the Aerodynamic Forces and Pressures Acting on a Semicylindrical Roof in Smooth Flow
Publisher: American Society of Civil Engineers
Abstract: The effects of surface roughness and Reynolds number on the characteristics of aerodynamic forces and pressures on a semicylindrical roof have been investigated in a wind tunnel. Simultaneous pressure measurements on smooth ...
Bond Property Test and Numerical Simulation of the Interface Layer between Asphalt Plug Joint and Pavement
Publisher: American Society of Civil Engineers
Abstract: The development and application of asphalt plug joints have gained popularity due to their unique advantages, such as driving comfort, shock absorption, noise reduction, and convenient management and maintenance. However, ...
Kriging–KNN Hybrid Analysis Method for Structural Reliability Analysis
Publisher: ASCE
Abstract: When the conventional response surface method is used to solve the reliability problem in complex structures, the response surface fitting accuracy is low, and the reliability accuracy does not satisfy the requirements of ...
Study on the Dynamic Characteristics and Damage Constitutive Model of Cemented Sand–Gravel
Publisher: American Society of Civil Engineers
Abstract: Cemented sand–gravel (CSG) is an innovative material for dam construction with a wide range of applications. Nevertheless, a comprehensive understanding of the dynamic properties of CSG is lacking. A series of cyclic ...
