RISScaling Anomaly in the Mechanical Response in Microscale Reverse Extrusion of Copper
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The continuing trend of device miniaturization brings increasing demand for small metal parts and, consequently, significant interest in microscale metal forming technologies. In this work, the influence of grain size on ...
Robust Tool Wear Monitoring Using Systematic Feature Selection in Turning Processes With Consideration of Uncertainties
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes a robust tool wear monitoring scheme for turning processes using low-cost sensors. A feature normalization scheme is proposed to eliminate the dependence of signal features on cutting conditions, cutting ...
KF-Based Multiscale Response Reconstruction under Unknown Inputs with Data Fusion of Multitype Observations
Publisher: American Society of Civil Engineers
Abstract: Utilization of multitype measurements including local and global information for structural health monitoring (SHM) has typically outperformed that using solo-type measurements. However, in many practical situations, only ...
Rolling Contact Fatigue Damage of High-Speed Railway Wheels With Upper Bainite
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work investigates the effect of abnormal microstructure on rolling contact fatigue (RCF) damage of high-speed railway wheels under service and the formation mechanism of abnormal microstructure by optical microscopy, ...
High-Order Large Eddy Simulations of a Wind Turbine in Ducted and Open-Rotor Configurations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: High-order large eddy simulations are performed to study the performance and flow fields of a ducted wind turbine (DWT) operating at different tip speed ratios. To evaluate the effects of the duct, simulations with the ...
Effect of Structure and Wearing Modes on the Protective Performance of Industrial Safety Helmet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study aims to explore the effects of helmet structure designs and wearing modes on the protective performance of safety helmets under the impact of falling objects. Four helmet types (no helmet, V-shaped, dome-shaped, ...
Effect of Flame–Wall Interaction on Blending Flame Characteristics in Ammonia and Methane Cofiring
Publisher: American Society of Civil Engineers
Abstract: AbstractAmmonia/methane cofiring is one of the effective solutions to low laminar burning
velocity and flame instability for the industrial application of ammonia energy, where
the wall limitation in the combustion chamber ...
Macro–Micro Characteristics of Eco-Friendly Geopolymer Incorporating Cement Paste Recycled Powder
Publisher: American Society of Civil Engineers
Abstract: AbstractReusing cement paste recycled powder (CRP) as a renewable binder in sustainable geopolymer
offers a valuable approach for recycling construction and demolition waste streams.
This study investigates the fresh, ...
Experimental and Numerical Study on Combustion Enhancement and Emission Reduction via Ammonia Preheating in Ammonia and Gasoline Dual-Fuel Engines
Publisher: American Society of Civil Engineers
Abstract: AbstractAmmonia (NH3) is considered an ideal alternative fuel for engines. However, with its combustion
characteristics, using NH3 in engines might lead to unstable combustion and the production of significant amounts
of ...
