Download or read book Consequences of the Thermal Effects Generated During Fatigue Crack Growth on the Mode One Stress Intensity Factor written by Zaid Boussattine and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: By subjecting a cracked specimen to a cyclic loading, thermal effects take place and create a heterogeneous temperature field around the crack tip. Those thermal effects are associated with coupling and dissipative heat sources, namely: (i) the heat source due to thermoelastic coupling generated by the hydrostatic part of the stress tensor related to cyclic mechanical loading; (ii) the heat source due to intrinsic dissipation associated with the self-heating phenomena originating from plasticity at the microscopic scale; (iii) and the heat source due to cyclic plasticity, at the macroscopic scale, which occurs in the reverse cyclic plastic zone ahead of the crack tip, and dissipates into heat. The overall heterogeneous temperature field resulting from the heat sources induces a heterogeneous stress field due to thermal expansion phenomena. As a consequence, the stress state over the crack is modified and leads to modify the stress intensity factor, which is a key parameter in modeling fatigue crack growth. Therefore, the aim of this PhD thesis is to quantify the consequences of the heat sources on the stress intensity factor, in the case of a long propagating fatigue crack.

Download or read book Nano and Microstructural Design of Advanced Materials written by M. A. Meyers and published by Elsevier. This book was released on 2003-12-05 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of the nanoscale effects has been recognized in materials research for over fifty years, but it is only recently that advanced characterization and fabrication methods are enabling scientists to build structures atom-by-atom or molecule-by molecule. The understanding and control of the nanostructure has been, to a large extent, made possible by new atomistic analysis and characterization methods pioneered by transmission electron microscopy. Nano and Microstructural Design of Advanced Materials focuses on the effective use of such advanced analysis and characterization techniques in the design of materials. - Teaches effective use of advanced analysis and characterization methods at an atomistic level - Contains many supporting examples of materials in which such design concepts have been successfully applied

Download or read book Effect of Warm Prestressing on Fatigue Crack Growth Curves at Low Temperatures written by A. Bussiba and published by . This book was released on 1985 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-temperature fatigue crack extension is studied in precracked single-edge-notched specimens of AISI 4340 steel. Steady-state crack extension in tension-tension fatigue and cyclic loading in conjunction with warm prestressing (WPS) are particularly emphasized. Effects of WPS on the fatigue crack growth curve are demonstrated and discussed. Special attention is given to the cleavage fracture mode, which dominates the features of the fatigue crack growth curve below the ductile-brittle transition (DBT) temperature. In AISI 4340 steel, which is characterized by DBT, WPS affects the alternative fracture mode and therefore alters the lower and upper bound values Kth and KIfc, respectively. For a more complete view, the behavior of AISI 304 stainless steel is discussed. The experimental results at low temperatures are mainly interpreted in terms of a transition in the cumulative crack tip damage process, induced by characteristic values of the stress intensity range amplitudes (?K).

Available in PDF, EPUB and Kindle. Book excerpt: UHMWPE Biomaterials Handbook describes the science, development, properties and application of of ultra-high molecular weight polyethylene (UHMWPE) used in artificial joints. This material is currently used in 1.4 million patients around the world every year for use in the hip, knee, upper extremities, and spine. Since the publication of the 1st edition there have been major advances in the development and clinical adoption of highly crosslinked UHMWPE for hip and knee replacement. There has also been a major international effort to introduce Vitamin E stabilized UHMWPE for patients. The accumulated knowledge on these two classes of materials are a key feature of the 2nd edition, along with an additional 19 additional chapters providing coverage of the key engineering aspects (biomechanical and materials science) and clinical/biological performance of UHMWPE, providing a more complete reference for industrial and academic materials specialists, and for surgeons and clinicians who require an understanding of the biomaterials properties of UHMWPE to work successfully on patient applications. - The UHMWPE Handbook is the comprehensive reference for professionals, researchers, and clinicians working with biomaterials technologies for joint replacement - New to this edition: 19 new chapters keep readers up to date with this fast moving topic, including a new section on UHMWPE biomaterials; highly crosslinked UHMWPE for hip and knee replacement; Vitamin E stabilized UHMWPE for patients; clinical performance, tribology an biologic interaction of UHMWPE - State-of-the-art coverage of UHMWPE technology, orthopedic applications, biomaterial characterisation and engineering aspects from recognised leaders in the field
