Grading Functions and Mesh Redistribution
SIAM Journal on Numerical Analysis, 1985Asymptotically optimal mesh gradings are derived for interpolation using \(H^ p\) seminorms. An algorithm for computing an interpolating mesh that approximately minimizes the \(H^ p\) seminorm of the error is obtained. An example illustrates some aspects of the procedure.

ABSTRACTThe bending response of functionally graded material (FGM) sandwich plates subjected to thermomechanical loads is investigated using a four-variable refined plate theory. A new type of FGM sandwich plate, namely, both FGM face sheets and an FGM hard core, is considered. Containing only four unknown functions, the governing equations are deduced

Functionally Graded Bioceramics
Materials Science Forum, 1999It has been the intention of the investigations discussed in the following to prepare graded hydroxyapatite/collagen I composites with osteoconductive properties which can be used as coatings for titanium implants or as hone replacements. Functionally graded multiphase calcium phosphate coatings can be applied for biocompatible coatings of metallic ...

The Stata Journal: Promoting communications on statistics and Stata, 2019
Student grade processing using Stata is more reliable than methods like spreadsheets and saves the user timeh, especially when courses are repeated. In this article, I introduce functions that automate some useful grade calculations: the functions curve grades according to combinations of a target grade mean, maximum, standard deviation, and ...

In modern engineering terminology, functionally graded materials (FGMs) refer to an advanced composite consisting of two or more phases. Thye are materials where the phases present are graded with spatial position within the structure. This chapter provides an overview of FGM and how it can be of benefit when utilized in engineering components ...

Functionally Graded Biocomposites
Materials Science Forum, 2012Functionally graded materials (FGM) are characterized by a gradual change in the volume fractions of two or more components as a function of position along certain dimensions. FGM has been introduced as an alternative to laminated composites where a mismatch in properties across each layer interface is the origin of stress concentration and a source of

This chapter introduces the concept of FGMs, along with a review of applications of such materials, their history, and the “traditional” methods used for the production of such a class of materials. The problems and the potential of this class of materials within additive manufacturing (printing of metals), with particular reference to 4-D printing ...

The objective of this chapter is to present the various analytical solutions for FGM beams based on the two-dimensional theory of elasticity. Solutions for the FGM beams were obtained by applying the displacement method (Sect. 4.1), the displacement function method (Sect. 4.2), the stress function method (Sect. 4.3), and the state space method (Sect. 4.

Functionally graded hardmetals
Journal of Alloys and Compounds, 2002Abstract One of the latest developments in the field of hardmetals and cermets used for metal cutting operations is the establishment of a functional gradient in near-surface areas of cutting tools leading to functional gradient hardmetals (FGHMs).
