The failure of any welded joint is at best inconvenient and at worst can lead to catastrophic accidents. Fracture and fatigue of welded joints and structures analyses the processes and causes of fracture and fatigue, focusing on how the failure of welded joints and structures can be predicted and minimised in the design process.Part one concentrates on analysing fracture of welded joints and structures, with chapters on constraint-based fracture mechanics for predicting joint failure, fracture assessment methods and the use of fracture mechanics in the fatigue analysis of welded joints. In part two, the emphasis shifts to fatigue, and chapters focus on a variety of aspects of fatigue analysis including assessment of local stresses in welded joints, fatigue design rules for welded structures, k-nodes for offshore structures and modelling residual stresses in predicting the service life of structures.With its distinguished editor and international team of contributors, Fracture and fatigue of welded joints and structures is an essential reference for mechanical, structural and welding engineers, as well as those in the academic sector with a research interest in the field. - Analyses the processes and causes of fracture and fatigue, focusing predicting and minimising the failure of welded joints in the design process - Assesses the fracture of welded joints and structure featuring constraint-based fracture mechanics for predicting joint failure - Explores specific considerations in fatigue analysis including the assessment of local stresses in welded joints and fatigue design rules for welded structures

The design of mechanical structures with improved and predictable durability cannot be achieved without a thorough understanding of the mechanisms of fatigue damage and more specifically the relationships between the microstructure of materials and their fatigue properties. Written by leading experts in the field, this book (which is complementary to Fatigue of Materials and Structures: Application to Damage and Design, also edited by Claude Bathias and André Pineau), provides an authoritative, comprehensive and unified treatment of the mechanics and micromechanisms of fatigue in metals, polymers and composites. Each chapter is devoted to one of the major classes of materials or to different types of fatigue damage, thereby providing overall coverage of the field. The book deals with crack initiation, crack growth, low-cycle fatigue, gigacycle fatigue, shorts cracks, fatigue micromechanisms and the local approach to fatigue damage, corrosion fatigue, environmental effects and variable amplitude loadings, and will be an important and much used reference for students, practicing engineers and researchers studying fracture and fatigue in numerous areas of mechanical, structural, civil, design, nuclear, and aerospace engineering as well as materials science.

Featuring contributions from industry leaders in their respective fields, this volume presents comprehensive, authoritative coverage of all the major issues involved in road vehicle dynamic behavior. It begins with a short history of road and off-road vehicle dynamics followed by thorough, detailed state-of-the-art chapters on modeling, analysis and optimization in vehicle system dynamics, vehicle concepts and aerodynamics, pneumatic tires and contact wheel-road/off-road, modeling vehicle subsystems, vehicle dynamics and active safety, man-vehicle interaction, intelligent vehicle systems, and road accident reconstruction and passive safety.

Avoiding or controlling fatigue damage is a major issue in the design and inspection of welded structures subjected to dynamic loading. Life predictions are usually used for safe life analysis, i.e. for verifying that it is very unlikely that fatigue damage will occur during the target service life of a structure. Damage tolerance analysis is used for predicting the behavior of a fatigue crack and for planning of in-service scheduled inspections. It should be a high probability that any cracks appearing are detected and repaired before they become critical. In both safe life analysis and the damage tolerance analysis there may be large uncertainties involved that have to be treated in a logical and consistent manner by stochastic modeling. This book focuses on fatigue life predictions and damage tolerance analysis of welded joints and is divided into three parts. The first part outlines the common practice used for safe life and damage tolerance analysis with reference to rules and regulations. The second part emphasises stochastic modeling and decision-making under uncertainty, while the final part is devoted to recent advances within fatigue research on welded joints. Industrial examples that are included are mainly dealing with offshore steel structures. Spreadsheets which accompany the book give the reader the possibility for hands-on experience of fatigue life predictions, crack growth analysis and inspection planning. As such, these different areas will be of use to engineers and researchers.

From weather-proof tires and artificial hearts to the o-rings and valve seals that enable successful space exploration, rubber is an indispensable component of modern civilization. Stiff competition and stringent application requirements foster continuous challenges requiring manufacturers to fund ever-expanding research projects. However, this vas

A multidisciplinary reference of engineering measurementtools, techniques, and applications—Volume 2 "When you can measure what you are speaking about, and expressit in numbers, you know something about it; but when you cannotmeasure it, when you cannot express it in numbers, your knowledgeis of a meager and unsatisfactory kind; it may be the beginning ofknowledge, but you have scarcely in your thoughts advanced to thestage of science." — Lord Kelvin Measurement falls at the heart of any engineering discipline andjob function. Whether engineers are attempting to staterequirements quantitatively and demonstrate compliance; to trackprogress and predict results; or to analyze costs and benefits,they must use the right tools and techniques to produce meaningful,useful data. The Handbook of Measurement in Science and Engineering isthe most comprehensive, up-to-date reference set on engineeringmeasurements—beyond anything on the market today. Encyclopedicin scope, Volume 2 spans several disciplines—MaterialsProperties and Testing, Instrumentation, and MeasurementStandards—and covers: Viscosity Measurement Corrosion Monitoring Thermal Conductivity of Engineering Materials Optical Methods for the Measurement of ThermalConductivity Properties of Metals and Alloys Electrical Properties of Polymers Testing of Metallic Materials Testing and Instrumental Analysis for Plastics Processing Analytical Tools for Estimation of ParticulateCompositeMaterial Properties Input and Output Characteristics Measurement Standards and Accuracy Tribology Measurements Surface Properties Measurement Plastics Testing Mechanical Properties of Polymers Nondestructive Inspection Ceramics Testing Instrument Statics Signal Processing Bridge Transducers Units and Standards Measurement Uncertainty Data Acquisition and Display Systems Vital for engineers, scientists, and technical managers inindustry and government, Handbook of Measurement in Science andEngineering will also prove ideal for members of majorengineering associations and academics and researchers atuniversities and laboratories.

Les aciers inoxydables duplex sont des alliages Fe-Cr-Ni-Mo dont l'utilisation s'est fortement accrue depuis 10 ans. Leur structure biphasée leur assure une plus haute résistance mécanique et une plus haute résistance à la corrosion que n'ont les aciers inoxydables austénitiques standard. Ces nuances duplex ont un succès commercial continument croissant pour un large domaine d'applications (secteurs énergétiques, industries du gaz et du pétrole, industries chimiques, chimiquiers, industries du papier et de la pâte à papier…), dû à leurs très bonnes propriétés et leur relativement faible coût.
