On the Stability of an Electrostatically-Actuated Functionally Graded Magneto-Electro-Elastic Micro-Beams Under Magneto-Electric Conditions
In this paper, the stability of a functionally graded magneto-electro-elastic (FG-MEE) micro-beam under actuation of electrostatic pressure is studied. For this purpose Euler-Bernoulli beam theory and constitutive relations for magneto-electro-elastic (MEE) materials have been used. We have supposed that material properties vary exponentially along the thickness direction of the micro-beam. Gov...
متن کاملTwo-Dimensional Elasticity Solution for Arbitrarily Supported Axially Functionally Graded Beams
First time, an analytical two-dimensional (2D) elasticity solution for arbitrarily supported axially functionally graded (FG) beam is developed. Linear gradation of the material property along the axis of the beam is considered. Using the strain displacement and constitutive relations, governing partial differential equations (PDEs) is obtained by employing Ressiner mixed var...

متن کاملElectrical and Mechanical Performance of Zirconia-Nickel Functionally Graded Materials
In the present work, six-layered (Zirconia/Nickel) functionally graded materials were fabricated via powder metallurgy technique (PMT). The microstructure, fracture surface and the elemental analysis of the prepared components were studied, and their linear shrinkage, electrical conductivity, fracture toughness and Vickers hardness were evaluated. The results show that the linear shrinkage of t...
متن کاملElastoplastic Analysis of Functionally Graded Beams under Mechanical Loads
Elastic-plastic behavior of a beam made of functionally graded material is investigated in this work. The beam is subjected to the constant axial and bending loads and the critical values of these loads for yield, collapse and elastic-plastic conditions are obtained. The variation of elastic modulus and yield strength through the height of the beam is determined with an exponential rule....
