Crack Evolution and Strength Attenuation of Red Clay under Dry–Wet Cycles
Publisher: ASCE
Abstract: Red clay is a special soil that loses water and shrinks easily, which causes expansion and contraction and leads to the generation and development of cracks, weakening the strength and engineering properties of the soil. ...
Effect of Ionic Emulsifiers on the Stability of Emulsified Asphalt Based on Molecular Dynamics Simulation
Publisher: American Society of Civil Engineers
Abstract: To investigate the effects of ionic emulsifiers on the stabilization of emulsified asphalt, this paper used the Materials Studio software package to model a two-layer structure consisting of asphalt-emulsifier-water-emul ...
Combined Computational and Experimental Studies on the Bending Cracking Behavior of Red Clay
Publisher: American Society of Civil Engineers
Abstract: This study investigates the factors affecting crack development in red clay roadbeds and slopes through a combined computational and experimental approach. A finite-element model of a prefabricated cracked red clay fracture ...
Wear Characteristics of Medical Hearing-Aid Components and Friction Reduction Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The wear characteristics of a hearing-aid battery assembly, which consist of an acrylonitrile-butadiene-styren (ABS) button cell compartment and a stainless steel bracket with the locking knob, have been studied in the ...
Predicting the Performance of System for the Co-production of Fischer-Tropsch Synthetic Liquid and Power from Coal
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A co-production system based on Fischer-Tropsch (FT) synthesis reactor and gas turbine was simulated and analyzed. Syngas from entrained bed coal gasification was used as feedstock of the ...
Mechanical Properties of Concrete with Al2O3 Hollow Sphere Added under Impact Loading
Publisher: American Society of Civil Engineers
Abstract: The aim of this paper was to study the mechanical properties and damage evolution of concrete added with Al2O3 hollow sphere (AHSC) under impact loading. The impact compression experiments were carried out by a 1-mm-diameter ...
Frequency Dependency and Constitutive Model of Dynamical Mechanical Properties of Cement Asphalt Binders
Publisher: ASCE
Abstract: Using the dynamic mechanical thermal analysis (DMTA) method, the frequency dependence of dynamic mechanical properties of cement asphalt (CA) binders were examined within the testing frequency range between 0.1 and 100 Hz ...
Effect of Antioxidant/CA-LDHs on the Properties of SBS-Modified Bitumen
Publisher: ASCE
Abstract: The cinnamic acid intercalated layered double hydroxides (CA-LDHs) were prepared by anion exchange method and analyzed by X-ray diffractometer (XRD) Fourier transform infrared (FTIR) spectrometer, scanning electron microscopy ...
