RISDisintegration of the K1 internal tide in the South China Sea due to parametric subharmonic instability
Publisher: American Meteorological Society
Abstract: The disintegration of the equatorward-propagating K1 internal tide in the South China Sea (SCS) by parametric subharmonic instability (PSI) at its critical latitude of 14.52°N is investigated numerically. The multiple-source ...
Inverse Estimation of Effective Thermal Conductivity of Multilayer Materials Considering Thermal Contact Resistance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Multilayer materials have been widely used in engineering applications, attributed to excellent thermo-mechanical performances. However, the thermal or mechanical properties of multilayer materials remain elusive, owing ...
Friction Variability in Slip Rings: Geometry and Stiffness Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study explores the frictional dynamics in wire-on-V-groove contacts, particularly in slip rings, by examining the effects of contact geometry and loading stiffness. Our experimental setup, using three different custom ...
Revealing the Tribochemical Evolution of PTFE Transfer Films During Ambient Aging
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Previous studies have established the critical role of tribochemistry in the formation of protective transfer films in dry friction applications of polytetrafluoroethylene (PTFE) composites. However, the specific mechanisms ...
Fast Response Gripper Based on Asymmetric Bistable Dual-Triangle Tensegrity Structure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Robots require compliant actuators capable of reducing tremendous stress shocks while maintaining fast response and lightweight. Bistable tensegrity structures have excellent performances such as fast response and high ...
Seismic Damage Investigation and Seismic Performance Study of Space Double-Layered Lattice Structure
Publisher: American Society of Civil Engineers
Abstract: With the rapid development of large-span space structures, it has become increasingly important to develop earthquake-resistance theory to a level that is much more safe under unexpected earthquake events. Motivation arises ...
Investigation on Dynamic Deformation and Damage of Steel Ribbon Wound Vessel for Hydrogen Storage Under Fragment Impact Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Steel ribbon wound vessels are a preferred type of hydrogen storage infrastructure in refueling stations. However, they may fail under the impact of fragments generated by nearby accidental explosions. This paper reports ...
Underlying Mechanisms of Improved Cryogenic Tribological Performance of the Pure Graphite: Suppressed Thermal Atomic Motions and Enhanced Mechanical Properties
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The cryogenic tribological performance of the pure graphite was investigated through experiments and molecular dynamics simulations in this study. As a brittle material, the pure graphite cooled by liquid nitrogen exhibited ...
Response of an Aluminum Stiffened Plate Under Extreme Slamming Loadings1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The slamming phenomenon often occurs when the bottom of a ship hits the seawater with a relatively high velocity in irregular waves. In extreme sea conditions, the slam-induced dynamic loads can be quite large resulting ...
Frictional Behaviors of 3D-Printed Polylactic Acid Components With Spiral-Groove Surface Textures Under Oil Lubrication
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the rapid development in additive manufacturing technology, three-dimensional (3D) printing process has been extensively utilized for the prototype manufacturing of industrial components. It is becoming possible and ...
