Book Synopsis Experimental and numerical investigation of ductile fracture initiation at low, intermediate and high strain rates by : Christian C.. Roth

This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse porte sur l'effet du taux de déformation sur l'initiation de la rupture ductile des métaux dans les aciers avancés à haute résistance (AHSS). Une analyse détaillée de la plasticité des AHSS (effet de la température et au taux de déformation) est requise, ainsi que la caractérisation de l'effet de l'état des contraintes. Les principaux résultats de cette thèse sont : (i) des essais novateurs pour déterminer la déformation à rupture dans les toles sous chargement proportionnel pour des chargements allant du cisaillement pur à la traction équi-biaxiale (ii) le développement d'une technique expérimentale permettant de réaliser des essais à rupture sur toles avec des barres de Hopkinson (SPHB) (iii)) un modèle de plasticité en grandes déformations incluant la dépendance au taux de déformation et à la température (iv) un modèle d'initiation de la rupture ductile dépendant du taux de déformation et (v) des observations micrographiques montrant une augmentation significative de la localisation de déformation à de forts taux de déformation. Outre une introduction générale, des conclusions, et un chapitre de perspectives, la thèse comprend quatre chapitres principaux: Dans le premier chapitre, un programme basique d'essais à rupture pour les toles est développé afin de caractériser l'amorce de la rupture ductile sous différents états de contraintes. Une éprouvette plane comportant deux sections utiles paralèlles est proposée pour déterminer la déformation à rupture pour des états de contraintes proches du cisaillement pur. Une méthodologie basée sur des simulations EF est développée pour optimiser la géométrie de l'éprouvette en fonction de la ductilité du matériau et de son écrouissage. Une éprouvette de traction trouée est optimisée pour déterminer la ductilité en traction uniaxiale. La déformation plane est étudiée par flexion d'une large bande, tandis qu'un essai de poinçonnement miniature est utilisé pour la traction equi-biaxiale. Dans un deuxième chapitre, un système d'inversion est développé pour des essais de traction à de forts taux de déformations avec des SPHB. Une barre de sortie située au-dessus de la barre d'entrée permet de mesurer l'effort de traction, tandis que le déplacement de l'éprouvette est mesuré par caméra rapide. Cette configuration permet une durée d'essais deux fois plus long qu'un système conventionnel de Kolsky, et des essais à des taux intermédiaires (~100/s) sans augmenter la longueur totale du système. Dans un troisième chapitre, des essais de traction à divers taux de déformation sont réalisés sur des éprouvettes plates lisses, entaillées et trouées. La rupture est précédée d'une striction. Une approche hybride expérimentale et numérique est utilisée pour calculer la déformation à rupture. Une dépendance au taux de déformation et à la température de type Johnson-Cook avec un écrouissage combiné Swift-Voce est utilisée avec une loi d'écoulement anisotrope non-associée pour décrire précisément les champs locaux de déformation. Les variations de tempréatures ne sont pas calculées en résolvant le problème thermo-mécanique complet, mais au moyen d'une fonction de poids dépendant du taux de déformation. Ces résultats sont ensuite utilisés pour calibrer et valider une extension récente du modèle d'initiation de rupture d'Hosford-Coulomb, prenant en compte l'effet du taux de déformation. Dans un quatrième chapitre, des essais sur éprouvettes de cisaillement sont réalisés pour une large gamme de température et de taux de déformation. La déformation de l'éprouvette est soigneusement analysée par corrélation d'images numériques et par une approche hybride expérimentale et numérique. Des analyses EBSD sont réalisées sous la surface de rupture, mettant en évidence l'influence de la vitesse de chargement sur la déformation de la microstructure.

This book was released on 2012-12-06 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of the USA-Japan Joint Seminar on "Fracture Mechanics of Ductile and Tough Materials and Its Applications to Energy Related Structures". The seminar was supported jointly by the National Science Foundation of the United States and the Japan Society for the Promotion of Sciences. The seminar was held from November 12th to 16th, 1979, at Hayama, Japan, a picturesque resort town by the beach of Sagami Bay facing Mt. Fugi. The safety and integrity of the engineering structures for energy explora tion, energy production, and energy transportation are of utmost importance to our welfare. Both the United States and Japan are at the forefront of the re search on fracture mechanics and its applications to fracture prevention. Dur ing the past few years, major research efforts have been made in the areas of non-linear fracture mechanics and its applications to fracture initiation, slow crack growth, creep and fatigue. This joint seminar offered an unique opportunity for detailed exchange of information on current researches and fu ture efforts.

Book Synopsis Micromechanisms of Fracture and Fatigue by : Jaroslav Pokluda
Download or read book Micromechanisms of Fracture and Fatigue written by Jaroslav Pokluda and published by Springer Science & Business Media. This book was released on 2010-05-27 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Micromechanisms of Fracture and Fatigue forms the culmination of 20 years of research in the field of fatigue and fracture. It discusses a range of topics and comments on the state of the art for each. The first part is devoted to models of deformation and fracture of perfect crystals. Using various atomistic methods, the theoretical strength of solids under simple and complex loading is calculated for a wide range of elements and compounds, and compared with experimental data. The connection between the onset of local plasticity in nanoindentation tests and the ideal shear strength is analysed using a multi-scale approach. Moreover, the nature of intrinsic brittleness or ductility of perfect crystal lattices is demonstrated by the coupling of atomistic and mesoscopic approaches, and compared with brittle/ductile behaviour of engineering materials. The second part addresses extrinsic sources of fracture toughness of engineering materials, related to their microstructure and microstructurally-induced crack tortuosity. Micromechanisms of ductile fracture are also described, in relation to the fracture strain of materials. Results of multilevel modelling, including statistical aspects of microstructure, are used to explain remarkable phenomena discovered in experiments. In the third part of the book, basic micromechanisms of fatigue cracks propagation under uniaxial and multiaxial loading are discussed on the basis of the unified mesoscopic model of crack tip shielding and closure, taking both microstructure and statistical effects into account. Applications to failure analysis are also outlined, and an attempt is made to distinguish intrinsic and extrinsic sources of materials resistance to fracture. Micromechanisms of Fracture and Fatigue provides scientists, researchers and postgraduate students with not only a deep insight into basic micromechanisms of fracture behaviour of materials, but also a number of engineering applications.

Available in PDF, EPUB and Kindle. Book excerpt: Fracture in structural materials remains a vital consideration in engineering systems, affecting the reliability of machines throughout their lives. Impressive advances in both the theoretical understanding of fracture mechanisms and practical developments that offer possibilities of control have re-shaped the subject over the past four decades. The contributors to this volume, including some of the most prominent researchers in the field, give their long-range perspectives of the research on the fracture of solids and its achievements. The subjects covered in this volume include: statistics of brittle fracture, transition of fracture from brittle to ductile, mechanics and mechanisms of ductile separation of heterogenous solids, the crack tip environment in ductile fracture, and mechanisms and mechanics of fatigue. Materials considered range from the usual structural solids to composites. The chapters include both theoretical points of view and discussions of key experiments.
