RISLocal Stress-Field Reconstruction Around Holes in a Plate Using Strain Monitoring Data and Stress Function
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study reconstructs a two-dimensional stress field from measured strain data. The advantage of using stress functions is that the stress equilibrium and strain compatibility are automatically satisfied. We use the ...
Fatigue Crack Modeling and Simulation Based on Continuum Damage Mechanics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Numerical simulation of fatigue crack propagation based on fracture mechanics and the conventional finite element method requires a huge amount of computational resources when the cracked structure ...
Heat Flux Correlations for Condensation From Steam and Air Mixtures on Vertical Flat Plates
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, heat fluxes qc for condensation from steam and air mixtures on vertical flat plates were evaluated by using existing experimental data and qc correlations, in order to provide one of boundary conditions for ...
Elastic and Plastic Microscopic Undulation on the Surface of Polycrystalline Pure Titanium Under Tension
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Commercial pure titanium has been widely used in the aerospace, chemical, and biomedical industries because of its light weight, high corrosion resistance, high strength, high heat resistance, and good biocompatibility. ...
Standard Seawater Comparison of Some Recent Batches
Publisher: American Meteorological Society
Abstract: The comparison experiment results of the standard seawater (SSW) were presented for batches P90, P100, P104, P106, P108 P111, and P112. This work shows that the SSW batch-to-batch agreement was recently improved. The ...
Numerical Simulation for Vortex Structure in a Turbopump Inducer: Close Relationship With Appearance of Cavitation Instabilities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Unsteady cavitation phenomena such as rotating cavitation and cavitation surge are often observed in a turbopump inducer of a rocket engine, sometimes causing undesirable oscillation of the system. ...
Evaluation of Solid Waste Management System Using Fuzzy Composition
Publisher: American Society of Civil Engineers
Abstract: Evaluating the best alternative for a solid waste management system often requires decision makers to consider conflicting, vague, and uncertain information. Fuzzy set theory offers a possible means of managing these kinds ...
Internal Flow and Axial Thrust Balancing of a Rocket Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Large axial thrust is produced on the rotor assembly of high-pressure rocket pumps. Thus, to ensure the reliability of bearings supporting the high rotational speed rotor, precise axial thrust ...
Modified RAMS-Urban Canopy Model for Heat Island Simulation in Chongqing, China
Publisher: American Meteorological Society
Abstract: A single-layer urban canopy model was integrated into a nonhydrostatic meteorological model, the Regional Atmospheric Modeling System (RAMS). In the new model, called RAMS-Urban Canopy (RAMS-UC), anthropogenic heat emission ...
Environmental Impact of Solid Waste Treatment Methods in Korea
Publisher: American Society of Civil Engineers
Abstract: The environmental impact of various solid waste treatment methods being used in Korea was assessed to provide useful information for decision making in solid waste management strategy. Among the treatment methods considered, ...
