RISSingularity Consideration in Numerical Solution of Contact Stress Problems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper gives an account of different approaches to deal with the weak singularity in numerical methods of contact stress problems when the methods are based on the fundamental equation ...
A Simplified Approach to Predict Elastic Pressure Distribution in Non-Hertzian Contact Stress Problems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An approximate but simple method to predict elastic pressure distribution in non-Hertzian contact stress problems has been developed using the two-dimensional Hertz relations and experimentally ...
Numerical Study on Conjugate Heat and Mass Transfer Characteristics Around Thermosolutal Exchangers: Effect of Flow Parameters and Solid Block Arrangement
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of airflow characteristics within a slot-ventilated enclosure is carried out numerically to optimize the heat and contaminants’ removal rate where cold air is injected via an inlet port. The contaminated air is ...
Surface-Roughness Effects in Rolling Contact
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A theory of rolling contact is presented which deviates from past theories in two respects: (a) the contacting surfaces are not assumed to be topographically smooth, and (b) Coulomb’s law of ...
Random Process Model of Rough Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rough surfaces are modeled as two-dimensional, isotropic, Gaussian random processes, and analyzed with the techniques of random process theory. Such surface statistics as the distribution of summit ...
Explaining Internal Behavior in a Fuzzy If-Then Rule-Based Flood-Forecasting Model
Publisher: American Society of Civil Engineers
Abstract: This paper presents a popular fuzzy rule-based model for river flow forecasting for an Indian basin. To set up the fuzzy rules, a cluster estimation method is adopted to determine the number of rules and the membership ...
Coastal Wave-Height Statistics during Hurricane Ike
Publisher: American Society of Civil Engineers
Abstract: The statistical behavior of wave heights obtained from short-term (i.e., 30-min) wave records during Hurricane Ike was investigated. Spectral data from seven temporary pressure gauges and one National Data Buoy Center ...
Effect of Rotation on Leakage and Windage Heating in Labyrinth Seals With Honeycomb Lands
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One of the basic assumptions of the traditional labyrinth seal leakage calculation is that rotation has minimal or no effect on seal leakage. With the advancement of gas turbine technology, to achieve high performance, ...
Performance Evaluation of Micro-Textured Inserts Coupled With Solid Lubricants During the Sustainable Dry Machining of Inconel 825
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this research work, the turning of Inconel 825 has been carried out using uncoated and coated laser-textured hard tungsten carbide (WC) cutting inserts. The efficacy of uncoated textured inserts has been tried to improve ...
Coupled Instabilities of Lateral Torsional Buckling and Shear Buckling of Singly Symmetric Steel I-Girders: Experimental and Numerical Investigations
Publisher: American Society of Civil Engineers
Abstract: This paper investigates the potential to extend current design limits for transverse stiffener spacing and effective lateral unbraced lengths through experimental and numerical studies. The focus here is on noncompact and ...
