Book excerpt: Functionally graded materials are generally two-phase composites with continuously varying volume fractions. Used as coatings and interfacial zones, they help to reduce mechanically and thermally induced stresses caused by the material property mismatch and to improve the bonding strength. In this project some basic problems concerning fracture mechanics of graded materials are identified, general analytical methods for solving the related crack problems are developed, the singular behavior of the solutions for typical material nonhomogeneities is examined, and solutions of some benchmark problems are obtained. The results are intended to provide technical support for material scientists and engineers who are trying to develop methods for processing these materials and for design engineers who are interested in using them in technological applications. Typical applications of functionally graded materials include thermal barrier coatings of high temperature components in gas turbines, surface hardening for tribological protection, and as interlayers in microelectronic and optoelectronic components. The results found show that by eliminating the discontinuities in material property distributions the mathematical anomalies regarding the crack tip stress oscillations for the interface cracks and the nonsquare root singularities for cracks intersecting the interfaces are also eliminated. From the viewpoint of fracture mechanics the importance of this result lies in the fact that in analyzing the components involving functionally graded materials one can use the existing crack tip finite element modeling developed for ordinary square root singularities and apply the energy balance based theories of conventional fracture mechanics.

This book was released on 2014-09-23 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanical responses of solid materials are governed by their material properties. The solutions for estimating and predicting the mechanical responses are extremely difficult, in particular for non-homogeneous materials. Among these, there is a special type of materials whose properties are variable only along one direction, defined as graded materials or functionally graded materials (FGMs). Examples are plant stems and bones. Artificial graded materials are widely used in mechanical engineering, chemical engineering, biological engineering, and electronic engineering. This work covers and develops boundary element methods (BEM) to investigate the properties of realistic graded materials. It is a must have for practitioners and researchers in materials science, both academic and in industry. Covers analysis of properties of graded materials. Presents solutions based methods for analysis of fracture mechanics. Presents two types of boundary element methods for layered isotropic materials and transversely isotropic materials.

Available in PDF, EPUB and Kindle. Book excerpt: Seven years have elapsed since Dr. Renee Ford, editor-in-chief of Materials Technology, first suggested to me to publish a book on Functionally Graded Materials (FGMs). She said that the FGM concept, then largely unknown outside of Japan and a relatively few laboratories elsewhere, would be of great interest to everyone working in the materials field because of its potentially universal applicability. There was no book about FGMs in English at that time, although the number of research papers, review articles, and FGM conference proceedings had been increasing yearly. We discussed what the book should cover, and decided it should present a comprehensive description from basic theory to the most recent applications of FGMs. This would make it useful both as an introduction to FGMs for those simply curious about what this new materials field was all about, and also as a textbook for researchers, engineers, and graduate students in various material fields. The FGM Forum in Japan generously offered to support this publication program. is very difficult for an individual author to write a book that Because it covers such a wide range of various aspects of many different materials, I invited more than 30 eminent materials scientists throughout the world, who were associated with FGM research, to contribute selected topics. I also asked several leading researchers in this field to edit selected chapters: Dr. Barry H. Rabin, then at the U. S.

Available in PDF, EPUB and Kindle. Book excerpt: This 3-year research program focuses on micromechanics and fracture mechanics analyses of cracking in functionally graded coating/substrate systems used in turbine engines and wear-related applications. Functionally graded materials (FGMs) are new advanced composites whose composition varies from place to place according to performance requirements. Recent developments of FGMs have demonstrated that functionally graded materials have the potential to enjoy a wide range of thermal and structural applications including thermal barrier coatings, wear, oxidation and corrosion resistant coatings and metal/ceramic joining. The objectives of the study include: establishing a fundamental understanding of the relationship between coating composition and performance, quantifying the influence of coating gradation, evaluating the effect of metal plasticity and crack bridging, and predicting the fracture driving forces and fracture resistance curves. Emphases in this study is placed on delamination fracture and multiple cracking in FGM coatings. The fundamental understanding gained from this study may enable one to select coatings at the component design stage. The systematic model predictions and design charts for the thermomechanical behavior of the coating/substrate systems may provide guidance to the gradation design of functionally graded coatings. This study thus can have a significant impact on the developments of functionally graded materials in turbine engine and wear related applications.

Book Synopsis Fatigue Crack Propagation in Functionally Graded Materials by : Brett Kenneth Hauber
Download or read book Fatigue Crack Propagation in Functionally Graded Materials written by Brett Kenneth Hauber and published by . This book was released on 2009 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in the development and application of functionally graded materials (FGM) has increased in recent years, leading to their limited use in a number of commercial and military products. More recently, interest in the use of FGMs in aircraft fuselage structures as integrated thermal protection systems has also begun to develop. However, our limited ability to predict the nucleation and fatigue propagation of cracks in these materials limits the application of FGMs to non fracture critical structures, reducing the potential benefits of their incorporation. A first step toward addressing this technology gap is to evaluate whether linear elastic fracture mechanics methods, appropriately modified to account for material non homogeneity, can be used to predict fatigue crack propagation in an arbitrarily graded metal/ceramic FGM. This dissertation documents new developments for characterization and modeling of fatigue crack propagation in FGMs. Unique precracking and characterization methods, and a Paris equation dependent upon stress intensity and material phase volume fraction and gradients are developed for FGMs. Hybrid numerical experiments are used to develop and verify a multivariable regression (MVR) method for identifying the effective crack tip coordinates and accurately recovering stress intensity from 2-D crack tip displacement field measurements in FGMs. Numerical and experimental results for Ti-TiB FGM specimens validate the MVR method for recovery of stress intensity in FGMs when allowing for the presence of manufacturing-induced residual stresses. Predicted fatigue crack propagation rates also compare favorably with experimental results, but are limited in accuracy by the effects of residual stresses. Residual stresses modify crack tip stress intensities and their effects are only accountable here by using the MVR recovered stress intensities. The results suggest that a Paris equation including material gradients as independent variables is viable. However, an accurate means of accounting for residual stresses in arbitrary FGM forms must be developed if linear elastic fracture mechanics methods are to be used effectively, otherwise excessive experimental characterization of fatigue crack propagation properties would be required.
