Book Description
Fracture is a major cause of failure in metallic and non-metallic materials and structures. An understanding of the micro- and macro- mechanisms of fracture enables materials scientists to develop materials with high fracture resistance, which in turn helps engineers and designers to ensure the soundness and integrity of structures made from these materials. The International Congress on Fracture is held every four years and is an occasion to take stock of the major achievements in the broad field of fracture, to honour those who have made lasting contributions to this field, and to reflect on the future directions. ICF9 is published in six volumes covering the areas of:-- Failure Analysis, Remaining Life Assessment, Life Extension and Repair- Failure of Multiphase and Non-Metallic Materials- Fatigue of Metallic and Non-Metallic Materials and Structures- Theoretical and Computational Fracture Mechanics and New Directions- Testing and Characterization Methods, and Interfacial Fracture Mechanics- High Strain Rate Fracture and Impact Mechanics.

Book Description
Advances in Fracture Research, Volume 6, documents the proceedings of the 5th International Conference on Fracture (ICF5) held in Cannes, France, 29 March-3 April 1981. The conference was attended by 670 participants from 26 countries. The program consisted of plenary sessions with invited speakers, technical sessions with contributed papers, a poster session, and two round table discussions. This volume contains 14 papers that deal with topics such as advancements in fracture mechanics; the application of fracture mechanics in three areas: damage tolerance requirements for aircraft structures, toughness requirements for bridges and heat up and cool down schedule, and evaluation of in service NDE indications for nuclear pressure vessels; and the analysis of crack-tip stress and strain fields for stationary and growing cracks in inelastic solids under monotonic loading. Also included are papers on the impact of environment on fracture; the problem of fracture of large concrete structures; and microcracking in hydrogenated austenitic steels.
Ductile Fracture in Metal Forming
Author: Kazutake KomoriPublisher: Academic Press
ISBN: 0128147733
Category : Technology & Engineering
Languages : en
Pages : 296
Book Description
Ductile Fracture in Metal Forming: Modeling and Simulation examines the current understanding of the mechanics and physics of ductile fracture in metal forming processes while also providing an approach to micromechanical ductile fracture prediction that can be applied to all metal forming processes. Starting with an overview of different ductile fracture scenarios, the book then goes on to explain modeling techniques that predict a range of mechanical phenomena that can lead to ductile fracture. The challenges in creating micromechanical models are addressed alongside methods of applying these models to several common metal forming processes. This book is suitable for researchers working in mechanics of materials, metal forming, mechanical metallurgy, and plasticity. Engineers in R&D industries involved in metal forming such as manufacturing, aerospace, and automation will also find the book very useful. - Explains innovative micromechanical modeling techniques for a variety of material behaviors - Examines how these models can be applied to metal forming processes in practice, including blanking, arrowed cracks in drawing, and surface cracks in upset forging - Provides a thorough examination of both macroscopic and microscopic ductile fracture theory
Fracture Mechanics of Ductile and Tough Materials and its Applications to Energy Related Structures

Book Description
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.
Multiscale Deformation and Fracture in Materials and Structures
Author: T-J. ChuangPublisher: Springer Science & Business Media
ISBN: 0306469529
Category : Science
Languages : en
Pages : 451
Book Description
Modern Solid Mechanics considers phenomena at many levels, ranging from nano size at atomic scale through the continuum level at millimeter size to large structures at the tens of meter scale. The deformation and fracture behavior at these various scales are inextricably related to interdisciplinary methods derived from applied mathematics, physics, chemistry, and engineering mechanics. This book, in honor of James R. Rice, contains articles from his colleagues and former students that bring these sophisticated methods to bear on a wide range of problems. Articles discussing problems of deformation include topics of dislocation mechanics, second particle effects, plastic yield criterion on porous materials, hydrogen embrittlement, solid state sintering, nanophases at surfaces, adhesion and contact mechanics, diffuse instability in geomaterials, and percolation in metal deformation. In the fracture area, the topics include: elastic-plastic crack growth, dynamic fracture, stress intensity and J-integral analysis, stress-corrosion cracking, and fracture in single crystal, piezoelectric, composite and cementitious materials. The book will be a valuable resource for researchers in modern solid mechanics and can be used as reference or supplementary text in mechanical and civil engineering, applied mechanics, materials science, and engineering graduate courses on fracture mechanics, elasticity, plasticity, mechanics of materials or the application of solid mechanics to processing, and reliability of life predictions.
Fracture Analysis of Ductile Crack Growth in Weld Material from a Full-Thickness Clad RPV Shell Segment

ISBN:
Category : Compact tension specimen
Languages : en
Pages : 11
Book Description
Recent studies indicate that the onset of stable ductile tearing leads to crack-tip fields ahead of the growing crack and crack-tip profiles that differ from those of a stationary crack. Stable ductile tearing exposes additional volumes of material to elevated stresses as the crack advances, which alters the sampling of potential cleavage initiation sites on the microstructural level. Also, measured cleavage fracture toughness values for these specimens will be influenced by changes in crack-tip constraint conditions that occur with prior stable crack growth. Fracture analysis techniques for inclusion of ductile crack growth in finite-element analyses were evaluated through applications to a full-thickness clad beam specimen containing a shallow crack in material for which metallurgical conditions are prototypic of those found in reactor pressure vessels (RPVs) at beginning of life. The beam specimen, which experienced a significant amount of precleavage stable ductile tearing, was fabricated from a section of an RPV wall (removed from a canceled nuclear plant) that includes weld, plate, and clad material. Effects of precleavage tearing on estimates of fracture toughness were investigated using continuum damage models.
