Multigrid Computation of Flow Past Airfoil Using k-ε Turbulence Model
Publisher: American Society of Civil Engineers
Abstract: A method for calculating compressible turbulent flows around an airfoil is presented. A modified low-Reynolds-number
Algorithms for Generating Three-Dimensional Aggregates and Asphalt Mixture Samples by the Discrete-Element Method
Publisher: American Society of Civil Engineers
Abstract: An algorithm for generating three-dimensional aggregates was developed first in this study. This algorithm can model the various shapes, sizes, and angularity of coarse aggregates. The shapes, sizes, and angularity of the ...
Fast Estimation of Initial Costate for Time-Optimal Trajectory Based on Surrogate Model
Publisher: ASCE
Abstract: This study investigated the time-optimal low-thrust interplanetary transfer problem, and proposes a fast estimation method for guessing the initial costate and optimal transfer time based on a surrogate model, and applied ...
Investigation of the Accuracy of Fracture Energy in Evaluating the Low-Temperature Cracking Performance of Asphalt Mixture
Publisher: ASCE
Abstract: To study the reason why the evaluation result of fracture energy is sometimes inconsistent with in situ cracking, the accuracy of fracture energy in evaluating low-temperature cracking resistance of asphalt mixture was ...
Effect of Skeleton Networks on the Bearing Capacity of Large Stone Porous Asphalt Mixes Using the Discrete Element Method
Publisher: ASCE
Abstract: Large stone porous asphalt mixes (LSPMs) have the characteristics of large gaps, large content of coarse aggregate, and large particle size of coarse aggregate. Compared with the traditional asphalt-treated base (ATB), ...
Comparative Analysis of Aged-SBSMA Regeneration in Hot In-Place Recycling: Individual and Coupled Effects of Aromatic Oil and SBS/SBR Polymer Modifiers
Publisher: American Society of Civil Engineers
Abstract: Hot in-place recycling (HIR) technology provides an efficient approach to utilizing reclaimed asphalt pavement, with the main challenge being effective recycling of styrene-butadiene-styrene (SBS) modified asphalt (SBSMA). ...
Simplified Thermo–Hydro–Mechanical Coupling Modes for High-Temperature Tunnels in Naturally Fractured Rock Masses: A Combined DFN and ECM Approach
Publisher: American Society of Civil Engineers
Abstract: This study investigated the thermo–hydro–mechanical (THM) coupling behaviors in naturally fractured rock tunnels through an innovative integration of the discrete fracture network (DFN) model and the equivalent continuous ...
Shear Stress Calculation and Distribution in Variable Cross Sections of Box Girders with Corrugated Steel Webs
Publisher: American Society of Civil Engineers
Experimental Investigation on the Wave Elevation around a Semisubmersible in Monochromatic and Irregular Waves
Publisher: American Society of Civil Engineers
Abstract: In the present work, the wave elevation around a floating semisubmersible was experimentally studied in monochromatic and irregular waves. The effect of the direction of incident waves was considered by introducing five ...
Asphalt-Mixture Force Chains Length Distribution and Skeleton Composition Investigation Based on Computational Granular Mechanics
Publisher: ASCE
Abstract: In asphalt mixtures, external loading transfer paths can be deemed as force chains. The force chains difference can be used to evaluate skeleton structure. In this study, various asphalt mixture virtual specimens were ...
