Titre :	Plastic-buckling of rectangular plates under combined uniaxial and shear stresses
Type de document :	texte imprimé
Auteurs :	C. M. Wang, Auteur ; Aung, Tun Myint, Auteur ; S. Kitipornchai, Auteur
Article en page(s) :	pp. 892-895
Note générale :	Mécanique appliquée
Langues :	Anglais (eng)
Mots-clés :	Buckling Combined stress Plastic analysis Plates Shear deformation.
Résumé :	This paper is concerned with the plastic-buckling of rectangular plates under uniaxial compressive and shear stresses. In the prediction of the plastic-buckling stresses, we have adopted the incremental theory of plasticity for capturing the inelastic behavior, the Mindlin plate theory for the effect of transverse shear deformation, the Ramberg-Osgood stress–strain relation for the plate material, and the Ritz method for the bifurcation buckling analysis. The interaction curves of the plastic uniaxial buckling stress and the plastic shear buckling stress for thin and thick rectangular plates are presented for various aspect ratios. The effect of transverse shear deformation is examined by comparing the interaction curves obtained based on the Mindlin plate theory and the classical thin plate theory.
