RISMechanical Properties and Durability of Fiber Reinforced Alkali Activated Slag Concrete
Publisher: American Society of Civil Engineers
Abstract: Alkali activated slag (AAS) concrete can be considered as a more environmentally friendly alternative to conventional concrete. The presence of cracks in the concrete matrix can have major impacts on its mechanical properties ...
A New Support Vector Machine and Artificial Neural Networks for Prediction of Stuck Pipe in Drilling of Oil Fields
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Stuck pipe is known to be influenced by drilling fluid properties and other parameters, such as the characteristics of rock formations. In this paper, we develop a supportvectormachine (SVM) based model to predict stuck ...
Biaxial Fatigue of A533B Pressure Vessel Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The low-to-intermediate cycle fatigue behavior of A533B steel is investigated using solid round bar specimens tested in combined bending and torsion. Loadings are applied in-phase and 90 deg ...
A Model of Capillary-Driven Flow Between Contacting Rough Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A liquid film can flow between two solid surfaces in close proximity due to capillary effects. Such flow occurs in natural processes such as the wetting of soils, drainage through rocks, water rise in plants and trees, as ...
Smoothed Particle Hydrodynamics for the Rising Pattern of Oil Droplets
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The problem of rising droplets in liquids is important in physics and has had many applications in industries. In the present study, the rising pattern of oil droplets has been examined using the smoothed particle hydrodynamics ...
Evaluation of Granular Soil Abrasivity for Wear on Cutting Tools in Excavation and Tunneling Equipment
Publisher: American Society of Civil Engineers
Abstract: This paper presents an experimental study of tool wear and abrasivity of granular soils using a testing system specifically designed for the evaluation of wear on earth-moving machines, especially soft ground tunneling ...
Estimation of Maximum Annular Pressure during HDD in Noncohesive Soils
Publisher: American Society of Civil Engineers
Abstract: This study investigated the effectiveness of estimating the maximum allowable annular pressure during horizontal directional drilling (HDD) in noncohesive soils by using two theoretical cavity-expansion solutions (small ...
Carbonation Curing versus Steam Curing for Precast Concrete Production
Publisher: American Society of Civil Engineers
Abstract: An investigation was conducted into the beneficial utilization of captured
Elastic Contact Between a Geometrically Anisotropic Bisinusoidal Surface and a Rigid Base
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the current study, a semianalytical model for contact between a homogeneous, isotropic, linear elastic halfspace with a geometrically anisotropic (wavelengths are different in the two principal directions) bisinusoidal ...
A Full Scale Microcontroller Based Direct Methanol Fuel Cell Test Station
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The development of a direct methanol fuel cell requires a fully automatic test station for understanding its characteristic and behavior. A unique design of test station for operation of a ...
