Dynamic thermal buckling of functionally graded spherical caps / N. Sundararajan in Journal of engineering mechanics, Vol. 134 N°2 (Fevrier 2008) 

Public ISBD [article]  in Journal of engineering mechanics > Vol. 134 N°2 (Fevrier 2008) . - pp.206–209. Titre : Dynamic thermal buckling of functionally graded spherical caps Type de document : texte imprimé Auteurs : N. Sundararajan, Auteur ; M. Ganapathi, Auteur Année de publication : 2008 Article en page(s) : pp.206–209. Note générale : Mécanique appliquée Langues : Anglais (eng) Mots-clés : Buckling  Shells  Thermal  factors  Finite  element  method Résumé : In the present work, dynamic buckling behavior of clamped functionally graded spherical caps suddenly exposed to a thermal field is studied using the finite-element procedure. The material properties are graded in the thickness direction. The temperature load corresponding to a sudden jump in the maximum average displacement in the time history of the shell structure is taken as the dynamic buckling temperature. Numerical study is carried out to highlight the influences of shell geometries and material gradient index on the critical buckling temperature.
