RISAn 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 ...
Mitigating Soil Erosion Caused by Artificial Disturbances in Hilly Lake Environs: Scenario Approach to LID Planning
Publisher:
Abstract: Low-impact development (LID) is crucial to mitigate soil erosion during artificial disturbance in hilly lake environs. However, little research on LID practices focuses on their scenario functions on long-term soil erosion ...
Approximate Solution of the Varying Speed Impact of Three-Dimensional Bodies on the Water Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes an approximate solution for the varying speed impact of three-dimensional (3D) bodies on the water surface, with the assumptions that the fluid is considered to be incompressible, inviscid, weightless, ...
Impact of a Plate on an Asymmetric Water Wedge
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The impacts of a plate on an asymmetric water wedge with constant and varying speeds are studied in this paper by considering the fluid to be incompressible, inviscid, and weightless; the effect of surface tension to be ...
