RISTheoretical Analysis of the Joint Leakage in Shield Tunnel Considering the Typical Deformation Mode
Publisher: ASCE
Abstract: The joint leakage in a shield tunnel is a common defect and difficult to be accurately quantified due to the complex deformation mode and stress state, which seriously threatens the service performance of the tunnel lining. ...
Effect of Different Inlet/Outlet Port Configurations on the Thermal Management of Prismatic Li-Ion Batteries
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The performance and life cycle of Li-ion batteries are governed by the maximum temperature and uniformity of temperature distribution in the battery pack, and an efficient thermal management system is highly desired to ...

Publisher: American Meteorological Society
Rheological Characterization of Fine-Grained Sediments under Steady and Dynamic Conditions
Publisher: ASCE
Abstract: The objective of this study is to investigate the steady and dynamic rheological behavior and characteristics of fine-grained sediments. A series of laboratory tests were conducted using an Anton Paar MCR 102 rheometer to ...
Human–Machine System Modeling and Safety Risk Assessment in Construction Operations Incorporating Workers’ Performance Variability
Publisher: American Society of Civil Engineers
Abstract: The increasing involvement of diverse construction machines has significantly transformed construction operations. Within the nonlinear interaction of multiple worker and machine functions, workers’ performance exhibits ...
Influences of Tooth Crack on Dynamic Characteristics of a Multi-Stage Gear Transmission System Considering the Flash Temperature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The crack failure is prone to happen for the gear teeth under alternating loads. The crack reduces the time-varying meshing stiffness, thus causing changes in the system vibration responses. Moreover, the tooth friction ...
Steady Streaming around a Circular Cylinder near a Plane Boundary due to Oscillatory Flow
Publisher: American Society of Civil Engineers
Abstract: Steady streaming due to an oscillatory flow around a circular cylinder close to and sitting on a plane boundary is investigated numerically. Two-dimensional (2D) Reynolds-averaged Navier-Stokes equations are solved using ...
Thermal-Boundary-Layer Response to Convected Far-Field Fluid Temperature Changes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fluid flows of varying temperature occur in heat exchangers, nuclear reactors, nonsteady-flow devices, and combustion engines, among other applications with heat transfer processes that influence ...
Three-Dimensional Geometric Nonlinear Analysis of Composite Cable-Stayed Bridges Using a Refined Double-Beam Model
Publisher: American Society of Civil Engineers
Abstract: In this paper, a refined double-beam finite-element model is constructed for composite cable-stayed bridges. Using this refined model, the authors aimed at performing more accurate three-dimensional (3D) analyses of ...
Numerical Study of Landfill Gas Emissions through Three Earthen Landfill Covers
Publisher: ASCE
Abstract: The effects of different types of earthen landfill covers and vapor on landfill gas emissions are not well understood. In this study, an existing theoretical model of water and multicomponent gas (methane, carbon dioxide, ...
