Ultrasonics and Acousto-Optics for the Nondestructive Testing of Complex Materials



Nondestructive testing has become an essential tool for failure prevention, conditionbased maintenance, structural health monitoring, as well as for quality control during production processes. Ultrasound and Acousto-Optics are applied to examine the mechanical properties of isotropic and anisotropic materials, and also to detect material defects. Fiber reinforced composites are ubiquitous in many industries, yet the interaction of ultrasound with such mat ....etc

Micron sized polymeric particles in custom designed geometries and with tunable chemical anisotropy are expected to enable a variety of new technologies in diverse areas such as photonics, diagnostics and functional materials. Current approaches for particle synthesis are either batch processes or flow-through microfluidic schemes that are based on two-phase systems, limiting the throughput, shape and functionality of the particles. We report a one-phase method called Stop Flow Lithography (SFL) that combines the advantages of microscope projec ....etc

A new research thrust in the analysis of complex systems has been created and an undergraduate curriculum has been reinvigorated.This has been accomplished by implementing a model of Scholarship put forth by Boyer in his work 'Scholarship Revisited'.Information Technology is the proving ground for the scholarship of integration and, by consequence, a catalyst for new teaching,research and service efforts. While the standardization of legacy software places boundaries on disciplines, the utilization of information technologies at a fundamental l ....etc

Abstract

the present paper the problem is discussed on Tractor Engine Assembly & Testing. It has been seen that during the engine testing most of the time some engine fails. That means they may have a problem of seizing. In fact, the seizure of the engine is not taking place suddenly but some type of warning given by engine during testing conditions in terms of white smoke. In ....etc

COMPLEX PROGRAMMABLE LOGIC DEVICE


As chip densities increased, it was natural for the PLD manufacturers to evolve their products into larger (logically, but not necessarily physically) parts called Complex Programmable Logic Devices (CPLDs). For most practical purposes, CPLDs can be thought of as multiple PLDs (plus some programmable interconnect) in a single chip. The larger size of a CPLD allows we to implement either more logic equations or a more complicated design. In fact, these chips are large enough to replace dozens of the pesky p ....etc

Ultrasound and Acousto-Optics are applied to examine the mechanical properties of isotropic and anisotropic materials, and also to detect material defects. Fiber reinforced composites are ubiquitous in many industries, yet the interaction of ultrasound with such materials is particularly challenging because of effects such as surface roughness, the fact ....etc

The uniaxial extensional viscosity is a fundamental material property of a fluid which characterizes the resistance of a material to stretching deformations. For microstructured fluids, this extensional viscosity is a function of both the rate of deformation and the total strain accumulated. Some of the most common manifestations of extensional viscosity effects in complex fluids are the dramatic changes they have on the lifetime of a fluid thread undergoing capillary breakup. In a pinching thread, viscous, inertial and elastic forces can all r ....etc
