RISEfficiency Improvement of an Automatic Ball Balancer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An automatic ball balancer is a unique vibration suppression device for rotor systems. Theoretically, two balls in a cylindrical chamber of the rotor are located at the optimal positions on ...
Modeling the Size-Dependent Nanostructures: Incorporating the Bulk and Surface Effects
Publisher:
Abstract: To precisely model the size dependencies in nanostructures, the surface effect and bulk effect are incorporated. From the physical point of view, size dependencies stem from not only the surface, but also the bulk. The ...
Measurement and Simulation of Temperature Field of Concrete Box Girder in Northwest Severely Cold Area
Publisher: American Society of Civil Engineers
Abstract: This study evaluated the characteristics of temperature field distribution of the concrete box girder based on the middle bridge of Xiaosha River, and the effects of temperature in severely cold area were determined through ...
Water Circulation System of a Sunken Plaza Based on the Concept of a Sponge City Utilizing Groundwater
Publisher: ASCE
Abstract: The use of a natural and low-impact way of managing surface water and groundwater in a sunken plaza is meaningful for urban ecological development. To achieve water storage, purification, and recycling, this study investigated ...
Time-Dependent and Stress-Dependent Chloride Diffusivity of Concrete Subjected to Sustained Compressive Loading
Publisher: American Society of Civil Engineers
Abstract: This paper studies the chloride diffusivity of concrete subjected to long-term exposure in a simulated marine environment with sustained compressive loading for up to 224 days. A series of concrete prisms were loaded under ...

Assessing the Impacts of Future Climate Change on Hydrology in Huang-Huai-Hai Region in China Using the PRECIS and VIC Models
Publisher: American Society of Civil Engineers
Abstract: The climate change impact on hydrology in China’s Huang-Huai-Hai (H-H-H) region was assessed in this study. Both variations in mean monthly and annual runoff and occurrences of extreme events including flood and drought ...
Contact Overlap Calculation Algorithms and Benchmarks Based on Blocky Discrete-Element Method
Publisher: ASCE
Abstract: The mechanical response of granular materials has been investigated widely using discontinuous modeling, such as the discrete-element method (DEM). Contact detection and contact resolution have been critical issues when ...
Research on Fault Cutting Algorithm of the Three-Dimensional Numerical Manifold Method
Publisher: American Society of Civil Engineers
Abstract: The fault cutting algorithm is important when applying the three-dimensional numerical manifold method to engineering simulation. This paper presents a primary approach to the fault cutting algorithm, including data ...
Study on Gradual Fracture of Rock and Key Precursor Information before Peak Stress Based on AE Monitoring under True Triaxial Loading
Publisher: ASCE
Abstract: The deep surrounding rock under true triaxial stress is easy to break at the new excavation face, which will induce engineering disasters to threaten personnel and equipment. Many studies have shown that the intermediate ...
