RISArchitected Piezoelectric Metamaterial With Designable Full Nonzero Piezoelectric Coefficients
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Piezoelectric metamaterials have received extensive attention in the fields of robotics, nondestructive testing, energy harvesting, etc. Natural piezoelectric ceramics possess only five nonzero piezoelectric coefficients ...
Gust Factors and Turbulence Intensities for the Tropical Cyclone Environment
Publisher: American Meteorological Society
Abstract: Gust factors are used to convert peak wind speeds averaged over a relatively short period (e.g., 3 s) to mean wind speeds averaged over a relatively long reference period (e.g., 1 h) or vice versa. Such conversions are ...
Analytical Solutions for Stable and Unstable Period 1 Motions in a Periodically Forced Oscillator With Quadratic Nonlinearity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this note, a closedform solution of periodic motions in a periodically forced oscillator with quadratic nonlinearity is presented without any small parameters. The perturbation method is based on one harmonic term plus ...
Biased Information Passing Between Subsystems Over Time in Complex System Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During the early stage design of largescale engineering systems, design teams are challenged to balance a complex set of considerations. The established structured approaches for optimizing complex system designs offer ...
Dynamic Test and Analysis of T-type Rigid Bridge Damage due to Excess Vibration
Publisher: American Society of Civil Engineers
Abstract: Aimed at the excess vibration phenomenon in the operation process of one T-type rigid bridge, another bridge which with the same type of superstructure and slightly different foundation form was chosen for contrast. By ...
Effect of Acid Contamination on the Microscopic and Strength Properties of Tianjin Soft Clay
Publisher: American Society of Civil Engineers
Abstract: Acid contamination has a notable influence on the geotechnical properties of soil and this influence is strongly dependent on contamination concentration (pH) and contamination duration. To fully investigate the effect of ...
Molding Process Design for Asphalt Mixture Based on Response Surface Methodology
Publisher: American Society of Civil Engineers
Abstract: The values of key parameters, asphalt aggregate ratio, mixing/compacting temperature, striking/compacting times, and fiber content are usually determined according to bulk properties or empirical values when molding asphalt ...
Development of a Manufacturing Method for Truss Core Panels Based on Origami Forming
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Sandwich panels, for example, honeycomb structure, are widely used in various stages because they are lightweight and have high stiffness. Recently, an origami structure called truss core panel (TCP) has become known as a ...
Characterization of Flow under Different Geometric Properties and Reynold Numbers in Y-Junction Bifurcated Fractures
Publisher: ASCE
Abstract: Bifurcated fractures are the basic units of fracture networks. In this paper, a bifurcated fracture model is designed using Fluent software to characterize the fluid flow in a fracture network. The characterization of water ...
Reinforcement Effect of the Stepped-Alternating Vacuum Preloading Method on Dredged Fills
Publisher: ASCE
Abstract: Dredged fills have been widely used as a filling material to meet the demand for land resources during land reclamation in coastal areas. When the conventional vacuum preloading (CVP) method is used to reinforce dredged ...
