The strength of advanced ceramic breeder pebbles, consisting of Li4SiO4 and Li2TiO3 as well as lithium excessive Li2TiO3 was investigated with the focus on the influence of different relevant fabrication methods, compositions and after thermal annealing. Within this work, the failure mechanisms of the pebbles were determined as well as their causes. Regarding the long term stability of the pebbles it is clear that with the use of a suitable composition significant improvements can be achieved.

"La structure ne doit pas être une contrainte, mais un support de créativité. Maîtriser la résistance des matériaux et connaître les systèmes structuraux permet de mieux les utiliser et de concevoir des bâtiments équilibrés et innovants. Cet ouvrage, abondamment illustré, explique simplement le fonctionnement des structures, le comportement des matériaux et les principes de dimensionnement des bâtiments en s'appuyant sur des connaissances simples et sur des situations de la vie courante. Il démontre aussi pourquoi et comment les enjeux fondamentaux d'une conception structurelle doivent être abordés dès l'origine du projet. Les fondements de la résistance des matériaux sont, dans un premier temps, présentés à partir des notions de force et d'équilibre, de l'échelle de la structure jusqu'à celle du matériau. La compréhension des mécanismes physiques permet ensuite d'exposer en détail les enjeux des grandes familles de structures planes et d'évoquer le comportement des structures spatiales. Plusieurs réalisations emblématiques sont analysées afin d'illustrer les déclinaisons de grands principes de la résistance des matériaux. Cette nouvelle édition s'enrichit d'une soixantaine d'exercices - avec leurs corrigés - qui font appel au raisonnement et au calcul, mais aussi à l'expérimentation et à la manipulation. Leur niveau d'abstraction et de complexité croissant favorise la compréhension des phénomènes et facilite la mémorisation ainsi que la mise en situation des concepts. Ce manuel est un outil pratique pour tous les concepteurs qui doivent donner forme aux structures de bâtiment ou de génie civil. Il s'adresse également aux architectes et ingénieurs en formation, ainsi qu'aux enseignants." [Quatrième de couverture]

In the science of physics, elasticity is the ability of a deformable body (e.g., steel, aluminum, rubber, wood, crystals, etc.) to resist a distorting effect and to return to its original size and shape when that influence or force is removed. Solid bodies will deform when satisfying forces are applied to them. Elasticity solution of materials will be grouped in forms of linear and nonlinear elasticity formulations. The main subject of this book is engineering elasticity and consists of five chapters in two main sections. These two main sections are ""General Theorems in Elasticity"" and ""Engineering Applications in Theory of Elasticity."" The first chapter of the first section belongs to the editor and is entitled ""Analytical and Numerical Approaches in Engineering Elasticity."" The second chapter in the first section is entitled ""A General Overview of Stress-Strain Analysis for the Elasticity Equations"" by P. Kumar, M. Mahanty, and A. Chattopadhyay. The first chapter of the second section is entitled ""FEA and Experimental Determination of Applied Elasticity Problems for Fabricating Aspheric Surfaces"" by Dr. D.N. Nguyen. The second chapter is entitled ""Concept of Phase Transition Based on Elastic Systematics"" by Dr. P.S. Nnamchi and Dr. C.S. Obayi. The third chapter is entitled ""Repair Inspection Technique Based on Elastic-Wave Tomography Applied for Deteriorated Concrete Structures"" by Dr. K. Hashimoto, Dr. T. Shiotani, Dr. T. Nishida, and Dr. N. Okude. Finally, this book includes the basic principles of elasticity and related engineering applications about theory and design.

Graphic methods for structural design essentially translate problems of algebra into geometric representations, allowing solutions to be reached using geometric construction (ie: drawing pictures) instead of tedious and error-prone arithmetic. This was the common method before the invention of calculators and computers, but had been largely abandoned in the last half century in favor of numerical techniques. However, in recent years the convenience and ease of graphic statics has made a comeback in architecture and engineering. Several professors have begun using graphic statics in the classroom.and.studio environment. But until now, there had been no guidebook that rapidly brings students up to speed on the fundamentals of how to create graphical solutions to statics problems. Graphic Statics introduces all of the traditional graphic statics techniques in a parametric drawing format, using the free program GeoGebra. Then, advanced topics such as indeterminate beams and three dimensional curved surfaces are be covered. Along the way, links to wider design ideas are introduced in a succinct summary of the steps needed to create elegant solutions to many static equilibrium problems. Meant for students in civil and architectural engineering, architecture,and construction, this practical introduction will also be useful to professionals looking to add the power of graphic statics to their work.

This book presents the bending theory of hyperelastic beams in the context of finite elasticity. The main difficulties in addressing this issue are due to its fully nonlinear framework, which makes no assumptions regarding the size of the deformation and displacement fields. Despite the complexity of its mathematical formulation, the inflexion problem of nonlinear beams is frequently used in practice, and has numerous applications in the industrial, mechanical and civil sectors. Adopting a semi-inverse approach, the book formulates a three-dimensional kinematic model in which the longitudinal bending is accompanied by the transversal deformation of cross-sections. The results provided by the theoretical model are subsequently compared with those of numerical and experimental analyses. The numerical analysis is based on the finite element method (FEM), whereas a test equipment prototype was designed and fabricated for the experimental analysis. The experimental data was acquired using digital image correlation (DIC) instrumentation. These two further analyses serve to confirm the hypotheses underlying the theoretical model. In the book’s closing section, the analysis is generalized to the case of variable bending moment. The governing equations then take the form of a coupled system of three equations in integral form, which can be applied to a very wide class of equilibrium problems for nonlinear beams.
