Nonlinear Ultrasonic Investigation of Concrete Damaged under Uniaxial Compression Step Loading
Publisher: American Society of Civil Engineers
Abstract: This research explains an experimental investigation of the concrete applying nonlinear ultrasonic testing technique. Eighteen cubic specimens,
Synthesis of Double Wall Carbon Nanotubes Using Sulfur as Catalyst
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The requirements of simple and reliable protocols for the synthesis of nanostructures with controlled morphology continue to be a major challenge in nanoscale. We demonstrate a novel and simplified ...
Optimal Watershed Management for Reservoir Sustainability: Economic Appraisal
Publisher: American Society of Civil Engineers
Abstract: Accumulation of sediment from upstream agricultural land may shorten the lifetime of a reservoir and reduce its long-term benefits. This paper presents a framework for assessment of management strategies that simultaneously ...
Efficiency of Jet Pumps
Publisher: American Society of Civil Engineers
Abstract: A theoretical analysis and an experimental study on the efficiency of water jet pumps, where water is used for both the primary and secondary flows, are presented in this paper. The theoretical efficiency equations for ...
Flow and Heat Transfer of a Stably Stratified Fluid Through an Enclosure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flow of a stably stratified fluid, or thermocline, through a cubical enclosure with: (a) strongly conducting; and (b) weakly conducting side-walls, was investigated experimentally. The flow ...
Elastic-Plastic Analysis of Directionally Solidified Lamellar Eutectic Composites
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Yielding in a crystal structure occurs with plastic slip on preferential planes. It is similar to yielding on maximum shear planes in an isotropic continuum, but in this case the slip is ...
Combining Mathematical Programming and SysML for Automated Component Sizing of Hydraulic Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present a framework for automated component sizing to extend a designer's ability to evaluate a particular configuration during the architecture exploration phase of a ...
Numerical Analysis of Water Transport Through the Membrane Electrolyte Assembly of a Polymer Exchange Membrane Fuel Cell
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of water transport through membrane electrolyte assembly of a polymer exchange membrane fuel cell on cell performance has been studied by a one-dimensional, nonisothermal, steady-state ...
An Analysis of Turbulent Shear Stresses in Leakage Flow Through a Bileaflet Mechanical Prostheses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, estimates of turbulence were made from pulsatile flow laser Doppler velocimetry measurements using traditional phase averaging and averaging after the removal of cyclic variation. ...
