Convection Velocity of Vortex Structures in the Near Wake of a Circular Cylinder
Publisher: American Society of Civil Engineers
Abstract: The convection velocity of vortex structures in the near wake of a circular cylinder was experimentally investigated over the region
Design Guideline for Ball Impact Test Apparatus
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The ball impact test is developed as a package-level measure of the board-level reliability of solder joints in the sense that it leads to brittle intermetallic fracturing, similar to that ...
Characteristics of Steady Horseshoe Vortex System near Junction of Square Cylinder and Base Plate
Publisher: American Society of Civil Engineers
Abstract: This paper presents an experimental investigation on the characteristics of a horseshoe vortex system near the juncture of a square cylinder and a horizontal base plate, using particle image velocimetry and flow visualization ...
Investigations of Board-Level Drop Reliability of Wafer-Level Chip-Scale Packages
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present in this paper parametric studies of board-level reliability of wafer-level chip-scale packages subjected to a specific pulse-controlled drop test condition. Eighteen experiment cells, ...
Simultaneous Particle Image Velocimetry and Laser Doppler Velocimetry Measurements of Periodical Oscillatory Horseshoe Vortex System near Square Cylinder-Base Plate Juncture
Publisher: American Society of Civil Engineers
Abstract: This paper presents simultaneous measurements using particle image velocimetry (PIV) and laser Doppler velocimetry (LDV) techniques on the study of a horseshoe vortex system. The horseshoe vortex system is generated near ...
Characteristics and Modeling of Multiple Direction Optimized-Friction Pendulum System With Numerous Sliding Interfaces Subjected to Multidirectional Excitations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a base isolator called a multiple direction optimized-friction pendulum system (Multiple DO-FPS) with numerous sliding interfaces is proposed. To understand the mechanical behavior ...
Flow Characteristics around a Circular Cylinder Placed Horizontally above a Plane Boundary
Publisher: American Society of Civil Engineers
Abstract: Flow characteristics around a circular cylinder positioned near a plane boundary (on which laminar boundary layer flow develops in the absence of circular cylinder), are investigated for Reynolds numbers
Simple Cord Composites
Publisher: American Society of Civil Engineers
Abstract: The deformation response of a simple cord composite to an axial load and twisting moment was found analytically. The simple cord composite consists of a metallic cord surrounded by a concentric circular cylindrical matrix ...
Effect of Sisal Fibers on the Rheology of Cement Paste Plasticized by Polycarboxylate Superplasticizer
Publisher: ASCE
Abstract: Sisal fibers (SF) and polycarboxylate superplasticizers (PCE) contribute to the sustainable development of cementitious materials by improving and optimizing their hardening properties. In this study, the impact of SF and ...
