RISEffect of Foaming Agent on Physical and Mechanical Properties of Foamed Phosphogypsum
Publisher: ASCE
Abstract: Foamed phosphogypsum (FPG) has recently attracted extensive interest owing to its potential consumption of phosphogypsum and its substitution for traditional gypsum building materials. However, as an important component ...
Analysis of a Two Dimensional Aeroelastic System Using the Differential Transform Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the nonlinear responses of a typical twodimensional airfoil with control surface freeplay and cubic pitch stiffness in an incompressible flow. The differential transform (DT) method is applied to ...
Hierarchical Modeling Method for DEM Simulation and Its Application in Soil–Pile–Cap Interaction and Impact Case
Publisher: American Society of Civil Engineers
Abstract: By developing a hierarchical modeling method, using discrete element analysis software PFC3D, a discrete-element method (DEM) model can be built and solved more efficiently. In this method, smaller particles are used for ...
Downrange Estimation Based on Powered Explicit Guidance for Pinpoint Lunar Landing
Publisher: ASCE
Abstract: Onboard computation of a fuel-optimal steering law is a pivotal technology for future lunar and planetary campaigns with pinpoint landings. This paper proposes a method of downrange estimation based on improved powered ...
Visualization Investigation of the Plugging Effect on Open-Ended Pipe Pile Jacked in Transparent Sand
Publisher: ASCE
Abstract: This paper describes the findings of a study of the soil plugging progressive formation process during pipe pile penetration using a transparent soil model test. The objective of this study is to visually investigate the ...
Development of a Novel Type of Liquid Accelerator Based on Aluminum Sulfate and Its Accelerating Mechanism for Cement Hydration
Publisher: ASCE
Abstract: A novel chlorine- and fluorine-free liquid accelerator was developed in this study. The proportion of each component of the accelerator was determined using an orthogonal test method. Various additives’ impact on the cement ...
Diamond Wheel Dressing: A Comprehensive Review
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper provides a comprehensive review on the dressing techniques of diamond grinding wheels. The common techniques with different tools were discussed in detail, which included the bonded SiC and diamond abrasive ...
Reexamination of Lime Stabilization Mechanisms of Expansive Clay
Publisher: American Society of Civil Engineers
Abstract: For the purpose of understanding the mechanism that results from treating expansive soil with lime, a series of tests were conducted on selected Nanyang expansive clay. X-ray diffraction tests indicated that the major clay ...
Investigation of the Stress–Strain and Strength Behaviors of Ice Containing Methane Hydrate
Publisher: American Society of Civil Engineers
Abstract: Mechanical properties and deformation behaviors of methane hydrate are important to assess the stability of gas hydrate reservoirs. In this study, using a high-pressure and low-temperature triaxial testing apparatus, the ...
Effects of Air Flowrate on the Combustion and Emissions of Blended Corn Straw and Pinewood Wastes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This research investigated the effects of the specific primary (under-fire) air flowrate (m˙air) on the combustion behavior of a 50–50 wt % blend of raw corn straw (CS) and raw pinewood wastes in a fixed-bed reactor. This ...
