Use of Greenway Trails in Indiana
Publisher: American Society of Civil Engineers
Abstract: The quality of existing data about the use of urban trails is poor, and planners need better data to plan new trails and manage existing ones. This note presents descriptive analyses of pedestrian and bicycle traffic counts ...
A Nonlinear Fracture Mechanics Approach to Modeling Fatigue Crack Growth in Solder Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Predicting the fatigue life of solder interconnections is a challenge due to the complex nonlinear behavior of solder alloys and the importance of the load history. Long experience with Sn–Pb ...
Stochastic Characterization and Models to Predict Performance Uncertainty in Photonic Packages
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: There is considerable uncertainty in the prediction of performance of a system, due mainly to idealizations in geometry, material behavior, and loading history. Uncertainties in geometry can be ...
Approximate Theory for Radial Filtration/Consolidation
Publisher: American Society of Civil Engineers
Abstract: Approximate solutions are developed for filtration and subsequent consolidation of compactible cakes on a cylindrical filter element. Darcy's flow equation is coupled with equations for equilibrium stress under the conditions ...
Singularities at Solder Joint Interfaces and Their Effects on Fracture Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, we focus on investigating the nature of the stress and strain behavior in solder joints and their effect on the hybrid damage modeling approach, which is inspired by cohesive ...
Computational Modeling and Validation of the Encapsulation of Plastic Packages by Transfer Molding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents, discusses, and compares results from experimental and computational studies of the plastic encapsulation process for a 144-lead TQFP package. The experimental results were ...
Time-Accurate, 3-D Computation of Wire Sweep During Plastic Encapsulation of Electronic Components
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A computational technique is developed for accurate prediction of wire sweep during encapsulation of electronic components by transfer molding. The technique advances the current state-of-the-art ...
Emissions Reduction by Varying the Swirler Airflow Split in Advanced Gas Turbine Combustors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A staged combustor concept for reducing pollutant emissions is currently under investigation. A numerical study was performed to investigate the chemically reactive flow with liquid spray injection ...
Effect of Sulfate Attack on Reinforced Concrete Columns Confined with CFRP Sheets under Axial Compression
Publisher: ASCE
Abstract: Sulfate ions in saltwater can considerably deteriorate the strength and durability of reinforced concrete (RC). To date, there has been no study that systematically investigates the effects of a sulfate attack on the ...
