This book was released on 2013-04-17 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical Metrology for Fluids, Combustion and Solids is the first practical handbook that presents the assemblage of the techniques necessary to provide a basic understanding of optical measurement for fluids, combustion, and solids. The use of light as a measurement tool has grown over the past twenty years from a narrowly specialized activity to a mainstay of modern research today. Until recently, the knowledge that could be extracted from the light interaction of light with physical objects was limited to specialized activities. The invention of the laser, the computer and microelectronics has enabled a measurement revolution such that virtually every parameter of engineering interest can be measured using the minimally intrusive properties of light. The authors of this book's chapters are leaders in this revolution. They work on the front lines of research in government, industry, and universities, inventing yet more ways to harness the power of light for the generation of knowledge.

This book was released on 2018-06-19 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper the sensitivity of embedded fiber optic sensors to changes in modal characteristics of plates is discussed. In order to determine the feasibility of embedded fiber Bragg gratings for the detection of modal shapes and modal frequencies, a comparison of holographically imaged modes and the detected dynamic strain from embedded fiber optic Bragg gratings is made. Time averaged optical holography is used for the detection of mechanical defects, or damage, in various aerospace components. The damage is detected by measuring an alteration in structural dynamics, which is visually apparent when using time-averaged holography. These shifts in the mode shapes, both in frequency of the resonance and spatial location of vibration nodes, are caused by changes in parameters that affect the structure's mechanical impedance, such as stiffness, mass and damping, resulting from cracks or holes. It is anticipated that embedded fiber optic sensor arrays may also be able to detect component damage by sensing these changes in modal characteristics. This work is designed to give an initial indication to the feasibility of damage detection through the monitoring of modal frequencies and mode shapes with fiber optic sensors.

Available in PDF, EPUB and Kindle. Book excerpt: This book bridges the gap between theoretical concepts and their implementations, especially for the high-performance structures/components related to advanced composite materials. This work focuses on the prediction of various structural responses such as deformations, natural frequencies etc. of advanced composites under complex environments and/or loading conditions. In addition, it discusses micro-mechanical material modeling of various advanced composite materials that involve different structures ranging from basic to advanced, such as beams, flat and curved panels, shells, skewed, corrugated, and other materials, as well as various solution techniques via analytical, semi-analytical, and numerical approaches. This book: Covers micro-mechanical material modeling of advanced composite materials Describes constitutive models of different composite materials and kinematic models of different structural configuration Discusses pertinent analytical, semi-analytical, and numerical techniques Focusses on structural responses relating to deformations, natural frequencies, and critical loads under complex environments Presents actual demonstrations of theoretical concepts as applied to real examples using Ansys APDL scripts This book is aimed at researchers, professionals, and graduate students in mechanical engineering, material science, material engineering, structural engineering, aerospace engineering, and composite materials.

This book was released on 1995-08-31 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Bilayer Lipid Membranes. Structure and Mechanical Properties the authors use new methods of measurement, which they have themselves developed, to present an analysis of the relation between membrane structure and viscoelastic properties, in particular in the transversal direction. Hianik and Passechnik's approach is fundamentally different from the usual one, in that they analyze lipid bilayer dynamics during various modes of deformation, arriving at a new, `three-layer' model that accounts for the great heterogeneity of biomembranes. The macroscopic parameters of membranes have been measured using a wide variety of methods, leading to a discussion of the correlations between the parameters. There is also an extensive discussion of the dynamic changes in mechanical properties of lipid bilayers in the course of conformational transition of integral proteins. During the conformational changes of proteins, the structure of a bilayer undergoes a transition, reaching a new, stable membrane state. The book is the first to present a comprehensive analysis of long-distance interaction in lipid bilayers and of molecular mechanisms of mechanoreception. Audience: Scientists and graduate students working in biophysics, membranology, physiology, medicine, pharmacology, bioelectronics, electrochemistry, and colloid chemistry.
