A Fractal Analysis of Stiction in Microelectromechanical Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The strong adherence (stiction) of adjacent surfaces is a major design concern in microelectromechanical systems (MEMS). Advances in micromachine technology greatly depend on basic understanding ...
Three-Dimensional Molecular Dynamics Analysis of Atomic-Scale Indentation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The complete atomic-scale indentation cycle is analyzed using molecular dynamics simulations. A hysteresis is observed in the instantaneous normal force versus surface separation distance curve ...
Three-Dimensional Elastic-Plastic Fractal Analysis of Surface Adhesion in Microelectromechanical Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: High adhesion is often encountered at contact interfaces of miniaturized devices, known as microelectromechanical systems, due to the development of capillary, electrostatic, and van der Waals ...
Estimation of Degree of Consolidation for Vacuum Preloading Projects
Publisher: American Society of Civil Engineers
Abstract: The degree of consolidation is usually used as one of the criteria for assessing the effectiveness of soil improvement work using the fill surcharge or vacuum preloading method. It is also often used as a design specification ...
Sand Transportations and Deposition Characteristics in Multiphase Flows in Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Sand management strategies become an important study to be performed as part of multiphase flow assurance assessments during oil and gas project life and especially for subsea multiphase flow ...
Full-Scale Measurements of Wind Pressures on a Low-Rise Building during Typhoons and Comparison with Wind Tunnel Test Results and Aerodynamic Database
Publisher: ASCE
Abstract: This study investigated wind-induced pressures on an instrumented low-rise building with gable roof and roof overhang during Typhoons Mujigae and Sarika by means of full-scale measurements. Then, detailed wind tunnel tests ...
Wind Tunnel Investigations of Aeroelastic Electricity Transmission Tower under Synoptic and Typhoon Winds
Publisher: ASCE
Abstract: Wind tunnel tests of an aeroelastic tower model at a length scale of 1∶40 were conducted to investigate the dynamic responses of an electricity transmission tower under synoptic and typhoon winds. The aeroelastic tower ...
Provision of Reinforcement in Concrete Solids Using the Generalized Genetic Algorithm
Publisher: American Society of Civil Engineers
Abstract: A generalized genetic algorithm has been developed to find the global optimal reinforcement contents for a concrete solid structure subjected to a general three-dimensional (3D) stress field. Feasible solutions were examined ...
Experimental Study on Sand Transport Characteristics in Horizontal and Inclined Two-Phase Solid-Liquid Pipe Flow
Publisher: ASCE
Abstract: An experimental investigation on the hydraulic transport of sand particles in pipelines is presented in both horizontal and 30° upward inclined orientations. The pipe, with an internal diameter of 0.0254 m, had sand ...
