Public ISBD [article]  in Journal of engineering mechanics > Vol. 138 N° 2 (Fevrier 2012) . - pp.230-234 Titre : Large deflection of thin plates in convex or concave cylindrical bending Type de document : texte imprimé Auteurs : Vivek A. Jairazbhoy, Auteur ; Pavel Petukhov, Auteur ; Jianmin Qu, Auteur Année de publication : 2012 Article en page(s) : pp.230-234 Note générale : Mécanique appliquée Langues : Anglais (eng) Mots-clés : Deflection  Plates  Beams  Bending Résumé : Considered in this paper is a special case relating to the large deflection of a thin beam. One end of the beam is fixed (i.e., clamped) to a rigid wall, whereas the other end is placed on a flat surface of arbitrary orientation. In previous studies, unique and non-unique solutions to the deflected shape were derived for cases in which the curvature of the beam experiences at least one change in sign. In this paper, a special case is examined in which the curvature of the beam does not change sign. Experimental results from photographs of deflected beams are presented to support the numerical predictions. An excellent agreement was found between the photographed and the predicted shapes.
