RISInvestigation of Clamping Effect on the Welding Residual Stress and Deformation of Monel Plates by Using the Ultrasonic Stress Measurement and Finite Element Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Welding of nickelbased alloys is increasingly used in the industry to manufacture many important components of the marine industries, chemical processing, etc. In this study, a 3D thermomechanical finite element (FE) ...
Silica-Aerogel Cotton Composites as Sound Absorber
Publisher: American Society of Civil Engineers
Abstract: In the research reported in this paper, silica aerogel was synthesized in a cotton nonwoven mat (CNM) and then the composite was used as a sound absorber. The experimental data indicated that using aerogel as a coating on ...
Effect of Soil Density and Suction on the Elastic and Plastic Parameters of Unsaturated Silty Soil
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of an experimental study on the effect of suction and compaction pressure on the elastic and plastic parameters of unsaturated silty soil. The experimental tests were performed in a specially ...
Introducing Glory: A Novel Strategy for an Omnidirectional Spherical Rolling Robot
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes a prototype and analytical studies of a spherical rolling robot, a new design of an omnidirectional robot system. The robot can arbitrarily begin to move in any direction ...
Numerical Modeling of Air Losses in Compressed Air Tunneling
Publisher: American Society of Civil Engineers
Abstract: A numerical model has been developed to predict the air losses from tunnel face and perimeter walls in compressed air tunneling. The model can also predict the zone of ground influenced by air flow from the face and walls ...
Roscoe and Hvorslev Surfaces for Unsaturated Silty Soil
Publisher: American Society of Civil Engineers
Abstract: The existence and characteristics of Roscoe and Hvorslev state boundary surfaces for unsaturated silty soil have been investigated by conducting controlled-suction triaxial tests on samples of an unsaturated compacted silty ...
Stochastic Finite-Element Approach to Quantify and Reduce Uncertainty in Pollutant Transport Modeling
Publisher: American Society of Civil Engineers
Abstract: One of the important issues in simulation of contaminant transport in the subsurface is how to quantify the hydraulic properties of soil that are randomly variable in space because of soil heterogeneity. Stochastic approaches ...
Fluid-Structure Interactions in Pressure-Suppression Pools: Small-Scale Experiments and Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments were conducted in a laboratory scale system to investigate fluid structure interaction effects on hydrodynamically induced boundary pressure histories. A single flexible member—a clamped ...
Effect of Freezing on Stress–Strain Characteristics of Granular and Cohesive Soils
Publisher: ASCE
Abstract: To investigate the stress–strain behavior of frozen soils, a program of triaxial compression tests was designed and carried out on samples of unfrozen and frozen cohesive (CL) and granular (SP) soils and pure ice. The ...
Enhancing Resilience of Intermittent Water Supply Systems to Power Outages
Publisher: American Society of Civil Engineers
Abstract: An estimated 1.3 billion people in South Asia, Latin America, and Africa receive water for domestic purposes through piped networks for limited periods, referred to as intermittent water supply (IWS). Electricity ...
