RISComparison of Rotary and Linear Cutting Methodology in Determining Specific Cutting Energy of Granite
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Single polycrystalline diamond compact (PDC) cutting is a practical technique to understand the rock–tool interactions in drag-bit-type geothermal drilling operations. This paper introduces a rotary cutting method to ...
Torsional Analysis for Prestressed Concrete Multiple Cell Box
Publisher: American Society of Civil Engineers
Abstract: The softened truss model theory applied to a prestressed concrete multiple cell box is developed in this study. In this theory, the concrete torsional problem is solved by combining equilibrium and compatibility conditions ...
Quantifying Railway Ballast Degradation through Repeated Large-Scale Direct Shear Tests and Three-Dimensional Morphological Analysis
Publisher: American Society of Civil Engineers
Abstract: To investigate the mechanism and manifestation of ballast spoilage, this study introduces a novel approach using a repeated large-scale direct shear test (involving multiple large-scale direct shear tests on the same batch ...
Experimental Study on Microbially Induced Carbonate Precipitation Reinforcement of Silty Sand in an Artificial Seawater Environment
Publisher: American Society of Civil Engineers
Abstract: Microbially induced carbonate precipitation (MICP) is an eco-friendly technique for weak soil reinforcement. In this study, Sporosacina pasteurii was used to strengthen silty sand after multigradient domestication in an ...
Evaluation of High-Resolution Gridded Precipitation Data in Arid and Semiarid Regions: Heihe River Basin, Northwest China
Publisher: American Meteorological Society
Abstract: AbstractThe reliability of three satellite-derived precipitation products, Tropical Rainfall Measuring Mission (TRMM) 3B42 V7 and the Climate Prediction Center morphing technique (CMORPH) satellite-only (CMORPH-RAW) and ...
Bearing Capacity of Shallow Foundations in Unsaturated Soil Considering Hydraulic Hysteresis and Three Drainage Conditions
Publisher: American Society of Civil Engineers
Characterizing Mist Distribution in Through-Tool Minimum Quantity Lubrication Drills
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The mist distribution is a critical factor in through-tool minimum quantity lubrication (MQL) drilling since a small amount of lubricant is used. However, it has rarely been discussed because of the difficulty in measuring ...
Loading–Unloading Cycles of Three-Dimensional-Printed Built Bimaterial Structures With Ceramic and Elastomer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper studies the loading–unloading behaviors of a three-dimensional (3D)-printing built bimaterial structure consisting of an open-cellular plaster frame filled with silicone. The combination of the plaster (ceramic ...
Biotreatment of Mn2+ and Pb2+ with Sulfate-Reducing Bacterium Desulfuromonas alkenivorans S-7
Publisher: American Society of Civil Engineers
Abstract: Biotreatment of heavy metals in acid mine drainage (AMD) with sulfate-reducing bacteria (SRB) is considered the most promising technique in the ecological restoration of mines. In the present work, the authors evaluated ...
Integrated Analytical Model for Characterizing Stress Distribution of Geosynthetic-Reinforced and Pile-Supported Embankments
Publisher: ASCE
Abstract: This paper aims to present an integrated analytical model for geosynthetic-reinforced and pile-supported embankments (GRPSEs) by rationally combining the reinforced embankment, the pile-embedded soft soil foundation, the ...
