RISHigh-Order Time-Integration Schemes with Explicit Time-Splitting Methods
Publisher: American Meteorological Society
Abstract: New high-order time-integration schemes for fully elastic models are presented. The new schemes, formulated using the Richardson extrapolation that employs leapfrog-type schemes, can give a good performance for linear model ...
Investigation Into Mechanical Behavior of the Current Collector for the Molten Carbonate Fuel Cell Through Finite Element Analysis Using Hexahedral Mesh Coarsening
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The current collector for the molten carbonate fuel cell (MCFC), which is a repeated structure of sheared protrusions, is manufactured from the threestage forming process. For the precise and efficient simulation of the ...
Design Optimization of Gas Foil Thrust Bearings for Maximum Load Capacity1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The aim of the present study is to develop a design guideline to improve the load capacity of gas foil thrust bearings (GFTBs). The Reynolds equation for an isothermal isoviscous ideal gas calculates the gas film pressure. ...
A Numerical Modeling Study of Mesoscale Cyclogenesis to the East of the Korean Peninsula
Publisher: American Meteorological Society
Abstract: Numerical simulations and the analysis of observational data are employed to understand the mesoscale cyclogenesis in a polar airstream that occurred over the sea to the east of the Korean peninsula on 28?29 January 1995. ...
A Snow-Ratio Equation and Its Application to Numerical Snowfall Prediction
Publisher: American Meteorological Society
Abstract: This study 1) presents a logistic regression equation of the snow ratio (SR) for use in a conversion of numerically predicted precipitation amounts into snowfall depths and 2) examines the quality of snowfall-depth forecasts ...
A Probabilistic Environmentally Assisted Cracking Model for Steam Generator Tubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A probabilistic environmentally assisted cracking (PEAC) model was developed to describe the propagation of primary water stress corrosion cracking for Alloy 600 in rolltransition region of steam generator (SG), a severe ...
Weld Quality Prediction in Ultrasonic Welding of Carbon Fiber Composite Based on an Ultrasonic Wave Transmission Model
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Ultrasonic welding has been widely used in joining plastic parts since it is fast, economical, and suitable for automation. It also has great potential for joining thermoplastic composite structures in the aerospace and ...
Enhanced Performance of Ultrasonic Welding of Short Carbon Fiber Polymer Composites Through Control of Morphological Parameters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ultrasonic welding (USW) is one of the joining technologies that can be applied to short carbon fiber thermoplastic composites. In this study, the USW of Nylon 6 reinforced by short carbon fibers created using injection ...
Ultrasonic Welding of Carbon Fiber Reinforced Composite With Variable Blank Holding Force
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Energy directors (EDs) have been widely used in ultrasonic welding (UW) of polymers and polymer-based composites. They help concentrate the welding energy and localize the weld at the location where the EDs are present. ...
