Analyse par la méthode des élément finis du comportement vibratoire d´une barre en matériau FGM Al2O3 - SuS304

Abstract

This work aims to study the vibratory behavior of FGM materials and the gradual composition of the ceramic metal mixture constituting a cylindrical bar with external protection in ceramic and working under the influence of temperature, to model this structure A numerical analysis based on the finite element method version p is applied, A theoretical and kinematical study on the model is made for the establishment of the kinetic energy and the strain energy of the system necessary for the determination of equations of motion by the equations of Lagrange. A Mathcad program is developed for calculating the frequencies of the system according to the index representing the gradual composition of the metal-ceramic fraction volume for various temperatures. The interpretation of the results obtained shows the accuracy and efficiency of the p version of the finite element method used for this numerical analysis.
