RISCollapse-Resisting Mechanisms of Planar Trusses Following Sudden Member Loss
Publisher: American Society of Civil Engineers
Abstract: Progressive collapse incidents of truss structures are often reported; however, studies on the collapse resistance of truss structures are comparatively few. In order to investigate the collapse-resisting mechanisms of ...
Designing the Geometry of Compact Tension Specimens for Easy Fracture Toughness Measurement Using Reinforcement Learning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For composite laminates, a rising R-curve is observed for their fracture toughness under Mode I stress, which is important for a comprehensive failure analysis of the materials. Since it is laborious to measure the R-curve ...
Characterization of Friction Condition Transition by Phase Space Trajectories
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A starved lubrication experiment and analytical model have been developed to investigate the friction condition transition (FCT) at the interface between a piston ring and a cylinder liner with the piston ring reciprocating ...
Full-Range Behavior of Top-and-Seat Angle Connections
Publisher: ASCE
Abstract: This paper presents recent research carried out at the University of Sydney on the full-range behavior of top-and-seat angle connections. A total of 18 tests were conducted, covering two connection configurations and three ...
Experimental Full-Range Behavior Assessment of Bolted Moment End-Plate Connections
Publisher: American Society of Civil Engineers
Abstract: The paper summarizes experiments conducted at the University of Sydney on bolted moment end-plate connections. The overall context of this work was to obtain full-range moment-rotation curves of the connections which can ...
Expulsion Intensity Monitoring and Modeling in Resistance Spot Welding Based on Electrode Displacement Signals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Weld expulsion is one of the most common welding defects during the resistance spot welding (RSW) process, especially for high strength steels (HSS). In order to control and eventually eliminate weld expulsion in production, ...
A Novel Expulsion Control Strategy With Abnormal Condition Adaptability for Resistance Spot Welding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Welding expulsion is a common problem in the resistance spot welding (RSW) process, which severely impacts weld quality and surrounding facilities. Existing expulsion control strategies are ineffective for complex and ...
Friction Property of MoS2 Coatings Deposited on the Chemical-Etched Surface of Al–Si Alloy Cylinder Liner
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To enhance the friction property of Al–Si alloy cylinder liner in running-in period, MoS2 coatings were electrodeposited on the chemical-etched surface of cylinder liner. The friction coefficient decreased by 15% comparing ...
Spatial–Temporal Changes of Water Resources in a Typical Semiarid Basin of North China over the Past 50 Years and Assessment of Possible Natural and Socioeconomic Causes
Publisher: American Meteorological Society
Abstract: ydrological processes in most semiarid regions on Earth have been changing under the impacts of climate change, human activities, or combinations of the two. This paper first presents a trend analysis of the spatiotemporal ...
