RISThe Selective Cell-Based Smoothed Finite Element Method for Partitioned Semi-Implicit Fluid–Structure Interaction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. A selective cell-based smoothed finite element method (CSFEM) is incorporated into a partitioned semi-implicit coupling scheme for fluid–structure interaction (FSI) based on four-node quadrilateral element. The ...
Indenter Orientation-Dependent Scratch Behavior and Size Effect in Single Crystalline Copper
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The orientation of the pyramidal indenter critically influences slip system activation and dislocation accumulation, thereby complicating the interpretation of tribological responses at small deformation scales. ...
Simulation of Plasto Elastohydrodynamic Lubrication in a Rolling Contact
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Surface plastic deformation due to contact (lubricated or dry) widely exists in many mechanical components, as subsurface stress caused by highpressure concentrated in the contact zone often exceeds the material yielding ...
A Forward Sensitivity Analysis and Design of U-Shaped Bellows Considering the Radial Compensation Capability Under Internal Pressure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bellows serve as integral component within a piping system, which withstand radial displacement loads and internal pressure loads. This study investigates the sensitivity analysis of structure design parameters, such as ...
Simulation of Plasto Elastohydrodynamic Lubrication in Line Contacts of Infinite and Finite Length
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Line contact is common in many machine components, such as various gears, roller and needle bearings, and cams and followers. Traditionally, line contact is modeled as a twodimensional (2D) problem when the surfaces are ...
Plasto Elastohydrodynamic Lubrication in Point Contacts for Surfaces With Three Dimensional Sinusoidal Waviness and Real Machined Roughness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Efficiency and durability are among the top concerns in mechanical design to minimize environmental impact and conserve natural resources while fulfilling performance requirements. Today mechanical systems are more compact, ...
Experimental and Numerical Investigations of the Stribeck Curves for Lubricated Counterformal Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
