RISEffect of the Capillary Property of Porous Media on the Water Transport Characteristics in a Passive Liquid-Feed DMFC
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The porous diffusion medium (DM) used in fuel cells has a complex heterogeneous structure in which both hydrophilic and hydrophobic pores coexist. The capillary flow in such a mixed-wet DM is ...
Insight into Early-Age Performance of Cement Paste/Mortar with C-S-Hs-PCE and Aluminum Sulfate
Publisher: ASCE
Abstract: This work aimed to perform the insight into the performance at early age of cement paste/mortar with calcium silicate hydrate seeds–polycarboxylate (C-S-Hs-PCE) and aluminum sulphate. The performance was evaluated using ...
Staged Damage Behavior and Acoustic Emission Characteristics of Rock-Like Materials under the Coupled Effects of Clay Mineral Content and Uniaxial Loading
Publisher: ASCE
Abstract: In this work, we investigated the effects of clay mineral content on the mechanical damage behavior and cracking mechanism of rock-like specimens with different bentonite (montmorillonite) contents by performing uniaxial ...
Critical Instability and Dynamic Loading Laws of the Artificial Dam in the Coal Mine Underground Reservoir
Publisher: American Society of Civil Engineers
Abstract: Establishing underground reservoirs in coal mines to protect water resources has become a new option. Ensuring the stability of an artificial dam is crucial for the safe operation of underground water reservoirs. Therefore, ...
Experimental and Theoretical Study of Viscoelastic Dampers with Different Matrix Rubbers
Publisher: American Society of Civil Engineers
Abstract: Viscoelastic (VE) dampers are one of the most popular structural control devices, and serious efforts have been undertaken to develop their availability in civil engineering. However, the performance of VE dampers is ...
Effect of Geofoam on Vertical Stress Distribution on Buried Structures Subjected to Static and Cyclic Footing Loads
Publisher: American Society of Civil Engineers
Abstract: Buried structures, such as pipes and culverts, are extensively used for transportation applications. The existence of these structures within the soil mass causes a redistribution of stresses. The stiffness of the buried ...
Closure to “Progressive Development of Two-Dimensional Soil Arching with Displacement” by Jie Han, Fei Wang, Mahdi Al-Naddaf, and Chao Xu
Publisher: American Society of Civil Engineers
Two-Dimensional Soil-Arching Behavior under Static and Cyclic Loading
Publisher: American Society of Civil Engineers
Abstract: To investigate soil-arching behavior under localized loading, trapdoor tests were conducted in this study with a model ground subjected to repetitive static and cyclic loads considering the influence of loading magnitude, ...
Two-Step Seismic Calculating Method and Seismic Features of SRC-RC Hybrid Frame Structure
Publisher: American Society of Civil Engineers
Abstract: For further improving the seismic design of steel-reinforced concrete (SRC)—RC frame structures, a two-step seismic calculating method is proposed as a supplement to the current Chinese standard for structural seismic ...
Mechanical Failure Characteristics and Energy Dissipation Laws of the Coal–Concrete Combination under Impact Rates
Publisher: American Society of Civil Engineers
Abstract: Mining shallow coal seams and deep coal seams is obviously different. In the deep environment of a coal mine, the stress concentration degree is high, and the dynamic load with impact tendency is prominent. In the practice ...
