Tensile stiffness and deformation model of rubber isolators in tension and tension-shear states / Yang, Q. R. in Journal of engineering mechanics, Vol. 136 N° 4 (Avril 2010) 

Public ISBD [article]  in Journal of engineering mechanics > Vol. 136 N° 4 (Avril 2010) . - pp. 429-437 Titre : Tensile stiffness and deformation model of rubber isolators in tension and tension-shear states Type de document : texte imprimé Auteurs : Yang, Q. R., Auteur ; W. G. Liu, Auteur ; He, W. F., Auteur Article en page(s) : pp. 429-437 Note générale : Mécanique appliquée Langues : Anglais (eng) Mots-clés : Rubber  Isolation  Stiffness  Deformation  Tensile  stress. Résumé : The tensile stiffness and deformation model of rubber bearings are systemically researched in the paper, a series of basic concepts, such as origin tensile longitudinal elastic modulus, tensile stiffness factor, origin tensile stiffness, offset tension origin stiffness, etc. are suggested corresponding to the theoretical formula and the experimental estimation method. Based on the origin tensile stiffness and offset tension origin stiffness, the deformation calculating theories related to pure tensile state and tension-shear state of isolated bearing are established. The double stiffness model and original stiffness model are proposed to describe the tension properties of rubber isolators after the bearings yield. The vertical tensile stiffness, offset tension origin stiffness, and deformation tests are performed with nature rubber bearings and lead plug rubber bearings to verify the new concepts and computation model of rubber isolators. All test results show that the theories established in the paper are suitable to analyze the tensile stiffness and tensile deformation for rubber isolators.
