Dispersion of horizontally polarized shear waves in laminated plates / Brahim Mohammedi 

Public ISBD Titre : Dispersion of horizontally polarized shear waves in laminated plates Type de document : texte imprimé Auteurs : Brahim Mohammedi, Auteur ; K. Datta, Directeur de thèse Editeur : University of Colorado Année de publication : 1986 Importance : 76 f. Présentation : ill. Format : 27 cm. Note générale : Mémoire de Magister : Génie Mécanique : Colorado, University of Colorado : 1986 Bibliogr. f. 77 . Annexe f. 78 - 80 Langues : Anglais (eng) Mots-clés : Mechanical  engineering  ;  Laminated  plates  ;  Horizontally  --  polarized  shear  ;  Geometric  properties  ;  Material  properties  ;  Dispersion Index. décimale : M006486 Résumé : The propagation of horizontally polarized shear waves through a cell and sandwich composed of plates with different geometric and material properties has been studied. Each plate is assumed to be homogeneous, isotropic and linearly elastic. The dispersion relation is obtained by using exact solutions of the equation of motion derived from the classical elasticity theory involving infinitesimal deformations. The general model including alternate layers with the same thickness of anisotropic material has been considered. The general expression for the dispersion relation is obtained by using the propagator matrix for any number of cells. Numerical results are presented showing the dependence between the frequency and wavenumber with asymptotic behaviour at short wave lengths. Several plots for the displacement amplitude distributed along the thickness are presented showing interesting physical significance.
