This book was released on 1989 with total page 850 pages. Available in PDF, EPUB and Kindle. Book excerpt: Creep, fatigue and creep-fatigue tests with five and ten minutes hold time were conducted using smooth and modified keyhole compact tension specimens. Measurements were made of the crack initiation and propagation of a 2 1/4Cr-1Mo steel in the normalized and tempered condition and a 304 stainless steel in the annealed condition at temperature of 565$spcirc$C and 650$spcirc$C, respectively, in air. Stress redistribution times under creep loading were computed to establish the governing stress field for crack initiation and crack growth using the creep isochronous curves and an analytical solution. Smooth specimen test results were used to predict the crack initiation life under fatigue and creep-fatigue loading using the local strain approach and to predict the total life under creep loading using the reference stress approach. Microstructural analysis was carried out to identify the failure mechanisms. It was found that crack initiation occupied a major portion of the failure life under creep and creep-fatigue loading and that stress redistribution times were two orders of magnitude lower than the crack initiation times. Both materials were identified as creep-ductile, with reference stress-controlled initiation and growth behavior. Creep failure mechanism predominates after short hold times ($>$5 minutes). Creep cavitation was the failure mechanism in 304 stainless steel while exhaustion of matrix ductility with very little creep damage was the dominant failure node for 2 1/4Cr-1Mo steel under creep and creep-fatigue loading.

Available in PDF, EPUB and Kindle. Book excerpt: From concept to application, this book describes the method of strain-range partitioning for analyzing time-dependent fatigue. Creep (time-dependent) deformation is first introduced for monotonic and cyclic loading. Multiple chapters then discuss strain-range partitioning in details for multi-axial loading conditions and how different loading permutations can lead to different micro-mechanistic effects. Notably, the total-strain method of strain-range partitioning (SRP) is described, which is a methodology that sees use in several industries. Examples from aerospace illustrate applications, and methods for predicting time-dependent metal fatigue are critiqued.

Available in PDF, EPUB and Kindle. Book excerpt: About 35 years ago, thermal fatigue was identified as an important phenomenon which limited the lifetime of high temperature plant. In the intervening years many investigations have been carried out, primarily to give guidance on likely endurance (especially in the presence of time dependent deformation) but latterly, with the introduction of sophisticated testing machines, to provide knowledge of the underlying mechanisms of failure. A previous edited book (Fatigue at High Temperature, Elsevier Applied Science Publishers, 1983) summarised the state-of-the-art of high temperature fatigue testing and examined the factors influencing life, such as stress state, environment and microstructural effects. It also considered, in some detail, cyclic crack growth as a more rigorous approach to life limitation. The aim of the present volume (which in style and format follows exactly the same lines as its predecessor) is once again to pursue the desire to translate detailed laboratory knowledge into engineering design and assessment. There is, for example, a need to consider the limitations of the laboratory specimen and its relationship with engineering features. Many design procedures still rely on a simple endurance approach based on failure of a smooth specimen, and this is taken to indicate crack initiation in the component. In this volume, therefore, crack propagation is covered only incidentally, emphasis being placed instead on basic cyclic stress strain properties, non-isothermal behaviour, metallography, failure criteria and the need for agreed testing procedures.

This book was released on 2020-02-19 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains chapters with the results of the research into the creep effect in different materials (ceramics, metallic materials, polymers, organic materials) and presents the method for using the assessment based on creep tests and numerical calculations to determine the actual lifetime. This subject has relevance as a significant development of new materials in which the creep effect is a decisive factor for their durability within the design service life have been observed in recent years. Therefore, there is a great demand for knowledge of the actual performance of materials during and beyond the design service life. The book aims to provide readers, including but not limited to MSc and PhD students as well as research personnel and engineers involved in operation of power equipment, with the comprehensive information on changes in the performance of creep-resistant materials during service.

This book was released on 2013-10-22 with total page 747 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Research on the Strength and Fracture of Materials: Volume 2Bs—Fatigue contains the proceedings of the Fourth International Conference on Fracture, held at the University of Waterloo, Canada, in June 1977. The papers review the state of the art with respect to fracture in a wide range of materials such as metals and alloys. This volume is comprised of 85 chapters and opens by discussing the metallographic aspects of fatigue in pearlitic structures and the dislocation diffusion mechanism of fatigue crack formation. The reader is then introduced to localized plastic deformation and fracture in slip bands during fatigue loading of age hardening aluminum alloys; the microstructure of fatigue fracture surfaces in titanium; mechanisms of liquid metal embrittlement, stress corrosion cracking, and corrosion-fatigue; and the fatigue behavior of macroscopic slag inclusions in steam turbo-generator rotor steels. A model for fatigue crack initiation in polycrystalline solids is also described. This monograph will be a useful resource for metallurgists, materials scientists, and structural and mechanical engineers.

This book was released on 2012-12-06 with total page 781 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1979 the first InternationalSymposium on Low CycleFatigue and Elasto-Plastic Behaviour of Materials was held in Stuttgart, FRG. Since then research in low cycle fatigue has proceeded rapidly. The vital interest of engineers and researchers in communicating the rapid advances in the ongoing research in low cycle fatigue has encouraged me to initiate again the Second International Conference which was held in Munich, FRG, 7-11 September 1987. Failure in low cycle fatigue represents a serious problem in the design and opera tion of highly stressed structures. Under complex loading and environmental cir cumstances, especially for high temperature services, reliable life prediction can not be expected without detailed consideration of the failure mechanism and with out extensive use of mechanistic approaches. The purpose of this conference was to provide a forum to discuss the advances in recent research in the field of low cycle fatigue. The conference was intended to help to further bridge the gap between those who are involved in basic research, and the engineers who have to perform the design of highly stressed structural components.
