Parametric study on the dynamic instability behavior of laminated composite stiffened plate / Patel, S. N. in Journal of engineering mechanics, Vol. 135 N° 11 (Novembre 2009) 

Public ISBD [article]  in Journal of engineering mechanics > Vol. 135 N° 11 (Novembre 2009) . - pp. 1331-1341 Titre : Parametric study on the dynamic instability behavior of laminated composite stiffened plate Type de document : texte imprimé Auteurs : Patel, S. N., Auteur ; P. K. Datta, Auteur ; Sheikh, A. H., Auteur Article en page(s) : pp. 1331-1341 Note générale : Mécanique appliquée Langues : Anglais (eng) Mots-clés : Finite  element  method  Plates  Parameters  Stiffening. Résumé : This paper deals with the study of dynamic or parametric instability behavior of laminated composite stiffened plates with step-uniform and concentrated in-plane harmonic edge loading. The eight-noded isoparametric degenerated shell element and a compatible three-noded curved beam element are used to model the plate and the stiffeners, respectively. The method of Hill's infinite determinant is applied to analyze the dynamic instability regions. Numerical results are presented through convergence and comparison with the published results from the literature. The effects of parameters like loading type, stiffening scheme, lamination scheme, dynamic load factor, and boundary conditions are considered in the dynamic instability analysis of laminated composite stiffened plate. It has been shown that the type of loading and the width of loading have remarkable effect on the dynamic instability characteristics of the stiffened plate.
