Bleustein-Gulyaev waves in some functionally graded materials
Functionally Graded Materials are inhomogeneous elastic bodies whose properties vary continuously with space. Hence consider a halfspace (x2 > 0) occupied by a special Functionally Graded Material made of an hexagonal (6mm) piezoelectric crystal for which the elastic stiffness c44, the piezoelectric constant e15, the dielectric constant ǫ11, and the mass density, all vary proportionally to the ...
متن کاملFunctionally 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...
متن کاملDisk Vibration Analysis of Functionally Graded Materials
Perforated discs have many applications in different parts of industry. By making such disks of functionally graded materials, more capabilities can be obtained from them. Vibration analysis of these kinds of disks can help us make them more efficient. In this paper, modeling and evaluation of disk vibration of functionally graded materials with regard to thickness were carried out using Abaqus...
متن کاملAdiabatic Shear Bands in Functionally Graded Materials
The initiation and propagation of adiabatic shear bands (ASBs) in functionally graded materials (FGMs) deformed at high strain rates in plane-strain tension have been studied. An ASB is a narrow region, usually a few micrometers wide, of intense plastic deformation that forms after softening of the material due to its being heated up and the evolution of damage in the form of porosity has overc...
متن کاملThe method of fundamental solutions for transient heat conduction in functionally graded materials: some special cases
In this paper, the Method of Fundamental Solutions (MFS) is extended to solve some special cases of the problem of transient heat conduction in functionally graded materials. First, the problem is transformed to a heat equation with constant coefficients using a suitable new transformation and then the MFS together with the Tikhonov regularization method is used to solve the resulting equation.
