RISSubstructure Simulation of Inhomogeneous Track and Layered Ground Dynamic Interaction under Train Passage
Publisher: American Society of Civil Engineers
Abstract: The vibrations in track and ground induced by train passages are investigated by the substructure method with due consideration to dynamic interaction between an inhomogeneous track system comprising continuous rails and ...
Transient Lamb's Solution for Surface Strip Impulses
Publisher: American Society of Civil Engineers
Abstract: An alternative integral‐form solution of the Lamb's problem is developed for the transient response inside of the medium as well as at the surface, when subjected to impulsive/sudden application of surface strip loads. A ...
Enhancing the Aggressive Intensity of a Cavitating Jet by Introducing Water Flow Holes and a Long Guide Pipe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is known that the geometry of the nozzle has a great effect on the aggressive intensity of a cavitating jet. In previous reports, various nozzle geometries were proposed, and improvements made to the aggressive intensity ...
New Development in Studies on the Characteristics of Bolted Pipe Flange Connections in JPVRC
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with some studies carried out in the bolted flanged connection committee (BFC) in Japan Pressure Vessel Council (JPVRC) on the stress analysis of a pipe flange connection using ...
Preparation of a 3DOM Ni–YSZ Anode With a Dense YSZ Thin Electrolyte Layer for Solid Oxide Fuel Cells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A three-dimensionally ordered macroporous (3DOM) Ni–yttria stabilized zirconia (YSZ) anode with a YSZ thin electrolyte layer was developed by a colloidal crystal templating method in order to ...
Measuring Quality of Human Community Life by Spatial-Temporal Age Group Distributions—Case Study of Recovery Process in a Disaster-Affected Region
Publisher: American Society of Civil Engineers
Abstract: This study proposes an effective method of measuring the quality of a community, calculated from spatial-temporal age group distributions. For this purpose, niche indices, which are used in ecology, are employed as measurement ...
New Evaluation Method for Liquefaction of Ground Using Dynamic Liquefaction Analysis Method and Its Application
Publisher: American Society of Civil Engineers
Abstract: Nankai megathrust earthquakes are expected to occur with a return period of approximately 90–200 years along the fault of the Nankai Trough. Because they are interplate earthquakes, it is predicted that they will cause ...
Experimental and Numerical Investigations of Effects of Flow Control Devices Upon Flat Plate Film Cooling Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study deals with the experimental and numerical studies of the effect of flow control devices (FCDs) on the film cooling performance of a circular cooling hole on a flat plate. Two types of FCDs with different heights ...
Improvement of Turbine Vane Film Cooling Performance by Double Flow Control Devices
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study deals with the studies of the effect of double flowcontrol devices (DFCDs) on turbine vane film cooling. Aiming for improving film effectiveness, two semispheroid DFCDs per pitch were attached to the vane surface ...
