Functionally graded adherends in adhesive joints: An overview

Viscoelastic analysis of stress distribution in balanced and unbalanced adhesively bonded single-lap joints with functionally graded adherends under the Reddy model

In this study, shear and peel stress distributions in the viscoelastic adhesive layer of a single-lap joint (SLJ) with functionally graded (FG) adherends are investigated. The study focuses on the effect of different adherend profiles and material composition on the time-dependent stress concentration/distribution in balanced and unbalanced SLJs. For this purpose, the Reddy model is applied to ...

Experimental Fracture Mechanics of Functionally Graded Materials: An Overview of Optical Investigations

The experimental efforts towards understanding the fracture behavior of continuously graded Functionally Graded Materials (FGMs) using full-field optical methods are reviewed. Both quasi-static and dynamic fracture investigations involving mode-I and -II conditions are presented. FGM configurations with crack planes perpendicular to, parallel to, and inclined to the direction of compositional g...

Functionally Graded Materials

Thermoelastic simulation of functionally graded materials is practically important for engineers. Here, the extension and assembly of our two previous papers (Computational Mechanics 2006, 38, p51-60; Engineering Analysis with Boundary Elements 2008, 32, p704-712) is presented to evaluate the transient temperature and stress distributions in two-dimensional functionally graded solids. In this c...

Functionally Graded Rapid Prototyping

Functionally Graded Rapid Prototyping (FGRP) is a novel design approach and technological framework enabling the controlled spatial variation of material properties through continuous gradients in functional components. Such variations are traditionally achieved as discrete delineations in physical behavior by fabricating multiple parts comprised of different materials, and assembling them only...
