Book excerpt: Le développement de méthodes d'identification de paramètres de lois de comportement de matériaux est devenu primordial pour avoir accès à la connaissance complète du comportement. En effet, les méthodes de mesure optiques, comme la Corrélation d'Images Numériques, permettent d'obtenir les quantités cinématiques de la relation de comportement sous forme de champs de vecteurs. En revanche, les contraintes ne sont généralement pas mesurables et il est nécessaire d'identifier les paramètres de la loi de comportement du matériau considéré pour y avoir accès. Plusieurs méthodes ont vu le jour et permettent de répondre à cette problématique mais la plupart d'entre elles supposent une homogénéité du matériau. Ce mémoire traite de l'application de certaines de ces méthodes, notamment la méthode de l'écart à l'équilibre (MEQ) et la méthode de recalage de modèle éléments finis (MREF), dans des matériaux hétérogènes à microstructure complexe où les propriétés mécaniques évoluent spatialement dans le volume. L'objectif est d'identifier ces propriétés mécaniques locales qui régissent la cinématique mesurée de tels matériaux dans le cadre de l'élasticité linéaire isotrope. Dans un premier temps, les deux méthodes citées sont décrites, implémentées et comparées sur des cas simulés en 2D. La MREF est préférée à la MEQ car plus robuste vis-à-vis des incertitudes de mesure. Basée sur un formalisme itératif, une parallélisation de l'algorithme a été opérée pour diminuer le coût en temps de la méthode. Des expérimentations dans le plan sur des éprouvettes en polyuréthane où les hétérogénéités sont maîtrisées ont permis de valider la méthode. Enfin, deux applications en 3D sur un matériau en mousse polyuréthane et un composite à base de fibres de bois démontrent l'intérêt d'une telle méthode pour l'identification de propriétés mécaniques locales. La mise en évidence d'une relation entre les propriétés locales identifiées et les propriétés locales de la microstructure de ces matériaux est effectuée.

Available in PDF, EPUB and Kindle. Book excerpt: In the past twenty years, new experimental approaches, improved models and progress in simulation techniques brought new insights into long-standing issues concerning dislocation-based plasticity in crystalline materials. During this period, three-dimensional dislocation dynamics simulations appeared and reached maturity. Their objectives are to unravel the relation between individual and collective dislocation processes at the mesoscale, to establish connections with atom-scale studies of dislocation core properties and to bridge, in combination with modelling, the gap between defect properties and phenomenological continuum models for plastic flow. Dislocation dynamics simulations are becoming accessible to a wide range of users. This book presents to students and researchers in materials science and mechanical engineering a comprehensive coverage of the physical body of knowledge on which they are based. It includes classical studies, which are too often ignored, recent experimental and theoretical advances, as well as a discussion of selected applications on various topics.

Available in PDF, EPUB and Kindle. Book excerpt: Using plant material as raw materials for construction is a relatively recent and original topic of research. This book presents an overview of the current knowledge on the material properties and environmental impact of construction materials made from plant particles, which are renewable, recyclable and easily available. It focuses on particles and as well on fibers issued from hemp plant, as well as discussing hemp concretes. The book begins by setting the environmental, economic and social context of agro-concretes, before discussing the nature of plant-based aggregates and binders. The formulation, implementation and mechanical behavior of such building materials are the subject of the following chapters. The focus is then put upon the hygrothermal behavior and acoustical properties of hempcrete, followed by the use of plant-based concretes in structures. The book concludes with the study of life-cycle analysis (LCA) of the environmental characteristics of a banked hempcrete wall on a wooden skeleton. Contents 1. Environmental, Economic and Social Context of Agro-Concretes, Vincent Nozahic and Sofiane Amziane. 2. Characterization of Plant-Based Aggregates. Vincent Picandet. 3.

Book excerpt: In this book, the authors discuss testing of ballast, including the strength, deformation and degradation aspects of fresh and recycled ballast under monotonic and cyclic loading. The effectiveness of geosynthetics in stabilising recycled ballast has also been examined. A new stress-strain constitutive model for ballast incorporating particle breakage is presented. Finally, a new range of particle gradations, balancing the strength and permeability requirements, has been proposed for future rail tracks. This book is intended as a reference text for final year civil engineering students and postgraduates, and for practicing railway engineers with the task of modernizing existing designs.
