This book was released on 1996 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: The phenomena of creep, fatigue and creep-fatigue interaction in metallic materials are reviewed and studied with respect to the underlying physical processes. The book may be especially useful to those students and engineers who should get knowledge of two aspects of this topic as the book contains an analysis of the basic principles and assumptions of the mathematical modelling of the mechanical behaviour of a material and relates this to the metallurgical background of the processes of deformation, evolution of damage and failure.
Book Synopsis Fatigue under Thermal and Mechanical Loading: Mechanisms, Mechanics and Modelling by : J. Bressers
Download or read book Fatigue under Thermal and Mechanical Loading: Mechanisms, Mechanics and Modelling written by J. Bressers and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Symposium "Fatigue under Thermal and Mechanical Loading", held at Petten (The Netherlands) on May 22-24, 1995, was jointly organized by the Institute for Advanced Materials of The Joint Research Centre, E. C. , and by the Societe Fran~se de Metallurgie et de Materiaux. The fast heating and cooling cycles experienced by many high temperature components cause thermally induced stresses, which often operate in combination with mechanical loads. The resulting thermal / mechanical fatigue cycle leads to material degradation mechanisms and failure modes typical of service cycles. The growing awareness that the synergism between the combined thermal and mechanical loads can not be reproduced by means of isothermal tests, has resulted in an increasing interest in thermal and thermo-mechanical fatigue testing. This trend has been reinforced by the constant pull by industry for more performant, yet safer high temperature systems, pushing the materials to the limit of their properties. Dedicated ASTM meetings in particular have set the scene for this area of research. The proceedings of the symposium organized by D. A. Spera and D. F. Mowbray in 1975 provided a reference book on thermal fatigue which reflects the knowledge and experimental capabilities of the mid-seventies.
Book Synopsis An Integrated Approach to Creep-Fatigue Life Prediction by : P. Agatonovic

Available in PDF, EPUB and Kindle. Book excerpt: There has been special interest recently in developing new, reliable analytical design methods for components under higher temperature conditions. However, at present, the use of material properties is still limited to arrays of single characteristics which do not interact with each other. In this work, several creep fatigue experiments on smooth specimens of IN 800 H have been carried out at 830°C. In some tests, these have also been combined with inside hysteresis loops to investigate the different effects on deformation and damage behavior which originate in a creep and fatigue environment. As a result of these tests, it has been found that the material behavior under creep-fatigue conditions can be significantly changed compared to the material behavior under simple load conditions. Therefore there is a need for life analysis methods to be expanded to include possible variations in properties; for greater accuracy, the material properties must be treated as a complex interacting system of parameters. The examination has been extended to a typical component used under high-temperature conditions. The results of the numerical analysis show that the stress-strain history in the critical area of that component is not simply strain controlled, as it is in the typical laboratory creep-fatigue interaction life test containing a tensile or compressive dwell at constant peak strain level. At high temperatures, the conditions in the component are more severe, causing the life to be reduced compared with the typical laboratory test. In this paper, these conditions are successfully simulated with the help of a generalized Neuber law: ? . ?p = constant. Based on this ratio, the engineering method for evaluating component geometry and loading conditions and their effects on material behavior can be established.

Book Synopsis Creep and Fatigue in Polymer Matrix Composites by : Rui Miranda Guedes
Download or read book Creep and Fatigue in Polymer Matrix Composites written by Rui Miranda Guedes and published by Elsevier. This book was released on 2010-11-29 with total page 605 pages. Available in PDF, EPUB and Kindle. Book excerpt: Creep is the tendency of materials to deform when subjected to long-term stress, particularly when exposed to heat. Fatigue phenomena occur when a material is subjected to cyclic loading, causing damage which may progress to failure. Both are critical factors in the long-term performance and reliability of materials such as polymer matrix composites which are often exposed to these types of stress in civil engineering and other applications. This important book reviews the latest research in modelling and predicting creep and fatigue in polymer matrix composites. The first part of the book reviews the modelling of viscoelastic and viscoplastic behaviour as a way of predicting performance and service life. Part two discusses techniques for modelling creep rupture and failure. The final part of the book discusses ways of testing and predicting long-term creep and fatigue in polymer matrix composites. With its distinguished editor and international team of contributors, Creep and Fatigue in Polymer Matrix Composites is a standard reference for all those researching and using polymer matrix composites in such areas as civil engineering. Reviews the latest research in modelling and predicting creep and fatigue in polymer matrix composites A specific focus on viscoelestic and viscoplastic modelling features the time-temperature-age superposition principle for predicting long-term response Creep rupture and damage interaction is examined with particular focus on time-dependent failure criteria for lifetime prediction of polymer matrix composite structures illustrated using experimental cases

Download or read book Temperature-Fatigue Interaction written by L. Remy and published by Elsevier. This book was released on 2002-03-11 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains a selection of peer-reviewed papers presented at the International Conference on Temperature-Fatigue Interaction, held in Paris, May 29-31, 2001, organised by the Fatigue Committee of the Societé Française de Métallurgie et de Matériaux (SF2M), under the auspices of the European Structural Integrity Society. The conference disseminated recent research results and promoting the interaction and collaboration amongst materials scientists, mechanical engineers and design engineers. Many engineering components and structures used in the automotive, aerospace, power generation and many other industries experience cyclic mechanical loads at high temperature or temperature transients causing thermally induced stresses. The increase of operating temperature and thermal mechanical loading trigger the interaction with time-dependent phenomena such as creep and environmental effects (oxidation, corrosion). A large number of metallic materials were investigated including aluminium alloys for the automotive industry, steels and cast iron for the automotive industry and materials forming, stainless steels for power plants, titanium, composites, intermetallic alloys and nickel base superalloys for aircraft industry, polymers. Important progress was observed in testing practice for high temperature behaviour, including environment and thermo-mechanical loading as well as in observation techniques. A large problem which was emphasized is to know precisely service loading cycles under non-isothermal conditions. This was considered critical for numerous thermal fatigue problems discussed in this conference.

Book Synopsis Modeling Creep-Fatigue Behavior of Mod.9Cr-1Mo Steel by : Meimei Li
Download or read book Modeling Creep-Fatigue Behavior of Mod.9Cr-1Mo Steel written by Meimei Li and published by . This book was released on 2011 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents three models that were developed explicitly for predicting the creep-fatiguebehavior of Mod.9Cr-1Mo steel. The Cyclic Softening Model incorporated tensile strain hardening and creep deformation, and described the cyclic stress variation as a function of cycle number under hold-time creep-fatigue loading. The Stress Relaxation Model predicted the stress relaxation curve during the hold time of cyclic loading, based on the creep properties of the material. The Interactive Damage Rate Equation predicted the hold-time creep-fatigue life using a methodology, in which the key materials parameters were determined by the creep properties and continuous fatigue data. The model predictions captured the trends of creep-fatigue interaction in Mod.9Cr-1Mo steel, and were in good agreement with experimental data in the literature.
