RISNumerical Simulation and Modeling of Laminar Developing Flow in Channels and Tubes With Slip
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Analytical solutions for slip flows in the hydrodynamic entrance region of tubes and channels are examined. These solutions employ a linearized axial momentum equation using Targ's method. The momentum equation is subjected ...
Alternative Water‐District Organization: Screening‐Level Analysis
Publisher: American Society of Civil Engineers
Abstract: Several water‐district organization alternatives are investigated using data and demand functions from a municipal water district in Northern California. A mathematical program finds optimal seasonal allocations and water ...
Using Weigh-in-Motion Data to Determine Aggressiveness of Traffic for Bridge Loading
Publisher: American Society of Civil Engineers
Abstract: This paper presents results based on the analysis of an extensive database of weigh-in-motion (WIM) data collected at five European highway sites in recent years. The data are used as the basis for a Monte Carlo simulation ...
Estimating the Probabilistic Size and Shape Distributions of 3D Anomalies From Sectioning Measurements Using the Stereological Unfolding Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The accuracy of probabilistic risk assessment of rotor disks is strongly dependent on the accurate description of the size and shape distributions of anomalies in alloys. These size-shape ...
Failure Time Prediction of Deteriorating Fail-Safe Structures
Publisher: American Society of Civil Engineers
Abstract: Structural evaluation and design have been dominated by component safety checks. In fact, current reliability-based codes for buildings and bridges are largely limited to individual structural component checks and do not ...
Service-Life Prediction of Deteriorating Concrete Bridges
Publisher: American Society of Civil Engineers
Abstract: Experience has demonstrated that highway bridges are vulnerable to damage from environmental attack, such as alkali-silica reaction, corrosion, and freeze-thaw. To make rational decisions in a life-cycle cost perspective, ...
A Probabilistic Framework for Gas Turbine Engine Materials With Multiple Types of Anomalies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Some rotor-grade gas turbine engine materials may contain multiple types of anomalies such as voids and inclusions that can be introduced during the manufacturing process. The number and size ...
Liquid Freezing Dynamics on Hydrophobic and Superhydrophobic Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Survey and Evaluation of Damaged Concrete Bridges
Publisher: American Society of Civil Engineers
Abstract: It is well known that the U.S. bridge inventory stands in need of repair. For a rational allocation of U.S. investment resources to bridge maintenance, life cycle cost and probabilistic methods must be used. This requires ...
Importance of the Tail in Truck Weight Modeling for Bridge Assessment
Publisher: American Society of Civil Engineers
Abstract: To predict characteristic extreme traffic load effects, simulations are sometimes performed of bridge loading events. To generalize the truck weight data, statistical distributions are fitted to histograms of weight ...
