RISThermoelastic Asperity Contacts, Frictional Shear, and Parameter Correlations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A thermoelastic asperity contact model has been developed for two-dimensional problems. This model takes into account a steady-state heat transfer and the asperity distortion due to thermoelastic ...
A Three-Dimensional Thermal-Mechanical Asperity Contact Model for Two Nominally Flat Surfaces in Contact
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The rough surface contact in a tribological process involves frictional heating and thermoelastic deformations. A three-dimensional thermal-mechanical asperity contact model has been developed, which ...
An Element-Free Galerkin-Finite Element Coupling Method for Elasto-Plastic Contact Problems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The element-free Galerkin-finite element (EFG-FE) coupling method, combined with the linear mathematical programming technique, is utilized to solve two-dimensional elasto-plastic contact problems. ...
Multiscale Analysis on Two Dimensional Nanoscale Sliding Contacts of Textured Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nanoscale sliding contacts are the major factors that influence the friction and result in wear in micro/nanoelectromechanical systems. Many experimental studies indicated that some surface textures ...
Exergy Analysis of a Solar Heating System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Exergy destruction associated with the operation of a solar heating system is evaluated numerically via an exergy cascade. As expected, exergy destruction is dominated by heat transfer across ...
An EFG-FE Coupling Method for Microscale Adhesive Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An elastic adhesive contact model based on the element-free Galerkin-finite element (EFG-FE) coupling method is presented in this paper. The model is first validated though comparison to theoretical ...
Study on Contact Characteristic of Nanoscale Asperities by Using Molecular Dynamics Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The nanoscale contacts, which play a key role in nanotechnology and micro-/nanoelectromechanical systems, are fundamentally important for a wide range of problems including adhesion, contact ...
Two-Dimensional Adaptive-Surface Elasto-Plastic Asperity Contact Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When contact problems are solved by numerical approaches, a surface profile is usually described by a series of discrete nodes with the same intervals along a coordinate axis. Contact computation ...
Thermal Storage in the Walls of a Solar House
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Residential winter thermal energy storage features water encapsulated into 3-in. (7.6-cm) diameter plastic pipes, mounted into conventional stud wall cavities of a house. With an air solar ...
A Peak Shear Strength Criterion of Rock Joints Based on Brightness Area Percentage
Publisher: American Society of Civil Engineers
Abstract: The stability of rock masses is intricately tied to the peak shear strength (PSS) of rock joints. In this study, a novel criterion for accessing the PSS of rock joints is proposed based on a three-dimensional (3D) parameter ...
