RISNature of Wave Modes in a Coupled Viscoelastic Layer over Water
Publisher: American Society of Civil Engineers
Abstract: A theoretical study of wave modes in a system of layered materials is presented. The system consists of a floating linear viscoelastic layer over inviscid water. The viscoelastic cover is assumed to obey the Voigt constitutive ...
Numerical Simulation of a Single Stone Column in Soft Clay Using the Discrete-Element Method
Publisher: American Society of Civil Engineers
Abstract: The coupled discrete-element method–finite difference method (DEM–FDM) numerical modeling scheme was proposed to simulate a single stone column in soft clay according to the Universal Distinct Element Code (UDEC). The ...
Research on the Influence of Cellulose Fiber on the Performance of Steel Slag Cement Cementitious Materials
Publisher: ASCE
Abstract: The combination of steel slag and cement to prepare green cement-based materials can help with environmental pollution issues, but the effectiveness of the products suffers versus cement without steel slag. This paper ...
Searching for a Parking Spot in a Large City Center
Publisher: American Society of Civil Engineers
Abstract: This study aims to study the general behavior of drivers when searching for a parking lot. A sample investigation is conducted on the users of 18 selected parking lots in the Xicheng district of Beijing. The influencing ...
Empirical Dynamic Modeling of Friction Stir Welding Processes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Current friction stir welding (FSW) process modeling research is mainly concerned with the detailed analysis of local effects such as material flow, heat generation, etc. These detailed ...
Design and Implementation of Nonlinear Force Controllers for Friction Stir Welding Processes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In friction stir welding (FSW) processes, force control can be used to achieve good welding quality. This paper presents the systematic design and implementation of FSW force controllers. The ...
Surface Swelling Characteristics in Concrete under Salt Frost Exposure
Publisher: ASCE
Abstract: Salt scaling is a commonly observed durability issue in concrete exposed to a combined salt and frost attack. This damage is restricted to a very thin surface region causing the removal of mortar flakes. This study ...
Modeling and Prototype of a Machining Robot With R(3-RUHR)/UURP Hybrid Module
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hybrid mechanisms combine the advantages of serial mechanisms and parallel mechanisms and have better stiffness and a larger workspace. In this paper, a novel workspace strongly coupled machining robot mechanism with a ...
Mathematical Modeling and Experimental Validation for the Performance of Soil–Bentonite Cutoff Walls Considering Chemical Compatibility
Publisher: American Society of Civil Engineers
Abstract: The soil–bentonite cutoff wall (SB wall) is commonly employed as a barrier at contaminated sites. However, recent research has revealed that the performance of the SB wall material can significantly deteriorate due to the ...
Artificial Neural Network Prediction of Overtopping Rate for Impermeable Vertical Seawalls on Coral Reefs
Publisher: ASCE
Abstract: An artificial neural network (ANN) tool trained using a backpropagation algorithm was developed to predict the overtopping rate of impermeable vertical seawalls on coral reefs. The training database was produced from ...
