RISA Variational Upper-Bound Method for Plane Strain Problems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a variational upper-bound (VUB) method is proposed. It is the method that determines an upper-bound solution using variational calculus. By using the method, a set of so called ...
A New Mechanism of Asperity Flattening in Sliding Contact—The Role of Tool Elastic Microwedge
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on real-time observation of the workpiece surface in a series of Lo and Tsai’s (2002) compression-sliding experiment, it is found that the asperity contact area is much greater than that ...
Experimental Investigation of the Behavior of a Lattice Steel Column Repaired with Pultruded GFRP Profiles
Publisher: American Society of Civil Engineers
Abstract: In this paper, a series of joint tests and full-scale structural tests were performed to assess the effectiveness of pultruded glass fiber-reinforced polymer (GFRP) profiles for rehabilitating lattice steel columns. The ...
Dynamic Analysis of Geared Rotor-Bearing Systems by the Transfer Matrix Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An analytical study of the dynamic characteristics of a geared rotor-bearing system by the transfer matrix method is presented. Rotating shafts of the system are modeled as Timoshenko beams ...
Pushover Response of a Braced Frame with Suspended Zipper Struts
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results from an experimental pushover test on a one-third-scale model of a special inverted-V-braced steel frame with zipper struts. Zipper elements are vertical elements added at the intersections ...
Travel Demand Model for Beijing 2008 Olympic Games
Publisher: American Society of Civil Engineers
Abstract: The Beijing 2008 Summer Olympic Games was held from August 8 to 24, 2008, which definitely drew attention from all walks of life at home and abroad. Beijing 2008 Olympic Games was a great event, and there were huge demands ...
An Aerothermodynamic Analysis of Transonic Compressor Rotors Containing Three-Dimensional Shocks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on the basic aerothermodynamic equations in the differential and integral forms on an arbitrary stream surface in an arbitrary nonorthogonal curvilinear coordinate system derived in this ...
Effects of Blade Wrap Angle Influencing a Pump as Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A pump is not ideally designed to operate as a turbine. To improve the efficiency of a pump as turbine (PAT), the redesign of the PAT, according to the flow of the turbine, is required. ...
Influence of Blade Number on the Performance and Pressure Pulsations in a Pump Used as a Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The rotor-stator interaction of a rotating impeller and a stationary volute could cause strong pressure pulsations and generate flow induced noise and vibration in a pump used as a turbine ...
Bicycle Lane Condition and Distance: Case Study of Public Bicycle System in Xi’an, China
Publisher: American Society of Civil Engineers
Abstract: Urban road infrastructure has significantly affected the popularity and use of public bike-sharing systems in many cities. Using the bike-sharing system of Xi’an, China, as a case study, this paper aims to discuss how the ...
