Book Description
Scientific research on functionally graded materials (FGM's) looks at functions of gradients in materials comprising thermodynamic, mechanical, chemical, optical, electromagnetic, and/or biological aspects. This collection of technical papers represents current research interests with regard to the fracture behaviour of FGM's. The papers provide a balance between theoretical, computational, and experimental techniques. It also indicates areas for increased development, such as constraint effects, full experimental characterization of engineering FGM's under static and dynamic loading, development of fracture criteria with predictive capability, multiphysics and multiscale failure considerations, and connection of research with industrial applications.

Book Description
Since a formulated concept of functionally graded materials (FGMs) was proposed in 1984 as a means of preparing thermal barrier materials, a coordinated research has been developed since 1986. The 125 papers presented here present state of the art research results and developments on FGM from the past decade. A wide spectra of topics are covered including design and modeling, fracture analysis, powder metallurgical processes, deposition and spray processes, reaction forming processes, novel processes, material evaluation for structural applications, organic and intelligent materials. Three reviews associated with national research programs on FGMs promoted in Japan and Germany, and the historical perspective of FGM research in Europe are presented as well. The resulting work is recommended to researchers, engineers and graduate school students in the fields of materials science and engineering, mechanical and medical engineering.

Book Description
Functionally graded materials (FGMs) are special composites consisting of two constituent phases whose composition change continuously along one direction. The gradual transition in material properties alleviates thermal mismatch problems experienced by cladded and coated components. The microstructure of FGM is usually heterogenous and the dominant failure mode of FGM is the crack initiation and propagation from the inclusions. The interface crack problem is studied by examining the asymptotic behavior of stress and displacement fields around the crack in FGM, and by comparing the results with known solutions for bimaterial systems. The focus is on characterizing the influence of material nonhomogeneity on the fracture parameters, and determining the fracture strength of FGM under quasi-static and dynamic loading.

Book Description
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.

Book Description
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. Written by two authors with extensive international experience in academic and private research and engineering.
