Based on the third-order shear deformation theory (TSDT), this paper numerically investigates the natural frequencies and time response of three-layered annular plate with functionally graded materials (FGMs) sheet core and piezoelectric face sheets, under initial external electric voltage. The impressive material specifications of FGM core are assumed to vary continuously across the plate thic...

In this article, the prominence has been given to study the influence of skew angle on bending response of functionally graded material shell panels under thermo-mechanical environment. Derivation of governing equations is based on the Reddy’s higher-order shear deformation theory and Sander’s kinematic equations. To circumvent the problem of C1 continuity requirement coupled with the finite el...

Al/SiC functionally graded and metal-matrix composites were investigated through dynamic mechanical analyzer as a function of vibrating frequencies. It was found that internal frictions strongly dependent on material type frequency. Tan ? reached 30.4 × 10–3 21.2 10–3in FGM MMC, respectively, at frequency 1 Hz. The damping capacity decreased the increased to 10 Hz 30 Storage moduli 172 GPa 144 ...

In this paper dynamic analysis of multi-directional functionally graded panel is studied using a semi-analytical numerical method entitled the state-space based differential method (SSDQM) and comparative behavior modeling by artificial neural network (ANN) for different parameters. A semi-analytical approach which makes use the three-dimensional elastic theory and assuming the material propert...

A series of three articles present an innovative way to build advanced functionally graded materials (FGM) based on polymer/ceramic composites tailored by electrophoresis from the process principle their field grading application in power electronics. In this Part 2, it was studied impact a non-uniform electric high-k SrTiO3 particle organization within epoxy matrix. that purpose, DBC substrate...

Thermal residual stresses in functionally graded materials (FGMs) arise primarily from nonlinear spatial variations in the thermal expansion coecient, but can be signi®cantly adjusted by variations in modulus. Thermoelastic analysis of FGMs is complicated by such modulus gradients. A class of problems for which thermal stress solutions for materials with constant modulus can be used as a basis...

In this work, an implicit algorithm is used for analyzing the free dynamic behavior of Functionally Graded Material (FGM) plates. The Third order Shear Deformation Theory (TSDT) to develop proposed model. contribution, formulation written without any homogenization technique as rule mixture. Hamilton principle establish resulting equations motion. For spatial discretization based on Finite Elem...

Solid freeform fabrication (SFF), also termed as layered manufacturing, produces parts directly from a computer model without part-specific tooling and human intervention (Sachlos et al., 2003; Leong et al., 2003; Kim et al., 2009; Dwivedi and Kovacevic, 2004; Cai et al., 2003; Tian et al., 2002; Guo et al., 2002; Cawley, 1999; Calvert et al., 1998; Alimardani and Toyserkani, 2008; Alemohammad ...

The aim of this paper is to investigate the buckling behavior porous Functionally Graded Materiel (FGM) cylindrical shells based on Donnell shell theory. In context, we develop an explicit analytical expression which takes into consideration effect porosities through thickness structure and that elastic foundation using a modified power-law function models Winkler Pasternak, respectively. We us...

In the present study, three layers of the ascending aorta in respect to the time and space at various blood pressures have been simulated. Two well-known commercial finite element (FE) software have used to be able to provide a range of reliable numerical results while independent on the software type. The radial displacement compared with the time as well as the peripheral stress and von Mises...
