RISResearch on the Accelerated Life Test Method for Gaskets and the Verification of the Accuracy of the Life Prediction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bolted flanged connections are widely used in the petroleum and chemical industries. The gasket is the core component of bolted flanged connections. Accurate prediction of the gasket life is of great significance for the ...
Seismic Performance of Joint between Locally Reinforced Multichamber Concrete-Filled L-Shaped Steel Columns and H-Shaped Beams
Publisher: American Society of Civil Engineers
Abstract: AbstractOwing to their irregular geometry, L-shaped steel-tube concrete column frame joints
are prone to stress concentration at corners and welds, and the torsional performance
of L-shaped columns is poor, which may lead ...
An Improved Fourier–Ritz Method for Analyzing In-Plane Free Vibration of Sectorial Plates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A modified Fourier–Ritz approach is developed in this study to analyze the free in-plane vibration of orthotropic annular sector plates with general boundary conditions. In this approach, two auxiliary sine functions are ...
Regression Analysis of 3D Initial Geostress Field for Deep and Super-long Highway Tunnel
Publisher: American Society of Civil Engineers
Abstract: Based on the engineering-geological conditions and measured data of geostress in Cangling tunnel, each possible factor affecting the initial geostress field was discussed. On this basis, the established 3D simplified ...
Surface Wave Attenuation by Periodic Pile Barriers in Unsaturated Soil
Publisher: American Society of Civil Engineers
Abstract: Abstract Due to their attenuation zone characteristics, underground periodic barriers such
as row piles used to isolate surface wave propagation in soil have been attracting
increasing attention in recent years. However, ...
Time-Varying Formation Control for Heterogeneous Planar Underactuated Multivehicle Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a distributed control approach for time-varying formation of heterogeneous planar underactuated vehicle networks without global position measurements. All vehicles in the network are modeled as generic ...
Semi-Analytical Model for the Transient Analysis of the Pressure in Vertically Fractured Wells in Reservoirs Considering the Influence of Natural Fractures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In addition to artificial fractures generated by hydraulic fracturing technology, natural fractures distributed in reservoirs will also affect the fluid flow process. To study the transient behavior of the pressure in fluid ...
Experimental Investigation on Mechanical Properties of Karst Tunnel Concrete under the Coupling Action of Load and Corrosive Environment
Publisher: American Society of Civil Engineers
Abstract: AbstractKarst tunnels are frequently subjected to severe corrosion, resulting in mechanical
deterioration of the lining structure. This study systematically explores the synergistic
degradation mechanisms caused by eccentric ...
Influence of Main Swirler Vane Angle on the Ignition Performance of TeLESS-II Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to balance the low emission and wide stabilization for lean premixed prevaporized (LPP) combustion, the centrally staged layout is preferred in advanced aero-engine combustors. However, compared with the conventional ...
Origami Crash Boxes Subjected to Dynamic Oblique Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The energy absorption capacity of origami crash boxes (OCB) subjected to oblique loading is investigated in the present study. A conventional square tube (CST) with identical weight is employed as benchmark. The comparative ...
