Available in PDF, EPUB and Kindle. Book excerpt: TEM investigations have been performed on irradiated samples after deformation covering various testing conditions for different recrystallized Zr alloys. It is shown that for transverse tensile tests and internal pressure tests performed at 350°C, only basal channels are observed for strain levels up to uniform elongation, whereas only prismatic and pyramidal channels are observed for axial tensile test. Then, focusing on internal pressure testing, irradiation hardening and strain hardening behavior have been analyzed in detail and compared to TEM observations. It is proposed that dislocation channeling phenomenon leads to high strain incompatibility between channels and surrounding grains and therefore to high microscopic internal stresses. These high microscopic internal stresses are believed to induce strong kinematic hardening at the macroscopic scale, as suggested by the mechanical behavior analysis. Finally, a micro-mechanical model based on microscopic deformation mechanisms and using homogenization techniques is proposed, taking into account the observed channeling phenomenon.

Download or read book Image Correlation for Shape Motion and Deformation Measurements written by Michael A. Sutton and published by Springer Science & Business Media. This book was released on 2009-04-21 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Image Correlation for Shape, Motion and Deformation Measurements provides a comprehensive overview of data extraction through image analysis. Readers will find and in-depth look into various single- and multi-camera models (2D-DIC and 3D-DIC), two- and three-dimensional computer vision, and volumetric digital image correlation (VDIC). Fundamentals of accurate image matching are described, along with presentations of both new methods for quantitative error estimates in correlation-based motion measurements, and the effect of out-of-plane motion on 2D measurements. Thorough appendices offer descriptions of continuum mechanics formulations, methods for local surface strain estimation and non-linear optimization, as well as terminology in statistics and probability. With equal treatment of computer vision fundamentals and techniques for practical applications, this volume is both a reference for academic and industry-based researchers and engineers, as well as a valuable companion text for appropriate vision-based educational offerings.

This book was released on 2011 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zirconium alloys are used in the nuclear industry as cladding tubes to prevent the fissile material from leaking into the coolant as the first safety wall of nuclear fuel. More and more requirements on fuel performance lead to stronger mechanical solicitations and integrity of cladding tubes has to be guaranteed. In this framework, the polycrystalline models, which are based on plasticity mechanisms, have interesting advantages compared to phenomenological ones. Some previous studies have shown that a polycrystalline approach could be very useful to describe the mechanical behavior of zirconium alloys. This modelling strategy has been successfully applied to fresh material and also, more recently, to irradiated material. The micromechanical approach has been developed in the light of transmission electron microscopy (TEM) observations. These experiments have been achieved to identify the main deformation mechanisms, which occur in several grains of relaxed and crept Zircaloy-4 samples. The main purpose of this paper is to describe an improved micromechanical model able to reproduce both the anisotropic creep behavior and the elasto-plastic behavior of unirradiated recrystallized Zircaloy-4 at 400°C. Finally, the quantitative analyses, which have been carried out with TEM correspond well with the results provided by the micromechanical approach.

This book was released on 2005 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The deformation systems in hexagonal close-packed (hcp) metals are not as symmetrically distributed as in cubic ones. Furthermore, because the primary slip systems are not as numerous and are limited to deformations in the a direction, twinning competes with slip in plastic deformation and can, depending on the deformation conditions, play an essential role. In order to explain the conditions in Zirconium and Zircaloy, the well-established relationships of hcp metals are discussed and so are their dependencies on the metal-specific parameters of the hexagonal structure. The interactions between deformation mechanisms and texture formation on the one side and deformation mechanisms and mechanical anisotropy on the other can be likewise transferred to other hcp metals, if one takes into account the differences in dependence of the metal-specific parameters.

Available in PDF, EPUB and Kindle. Book excerpt: Annotation The 41 papers of this proceedings volume were first presented at the 13th symposium on Zirconium in the Nuclear Industry held in Annecy, France in June of 2001. Many of the papers are devoted to material related issues, corrosion and hydriding behavior, in-reactor studies, and the behavior and properties of Zr alloys used in storing spent fuel. Some papers report on studies of second phase particles, irradiation creep and growth, and material performance during loss of coolant and reactivity initiated accidents.
