Mathematical model of the rubber-cord shell of rotation for pneumatic dampers by V. S. Korneyev, V. V. Shalay

“…The review of the fundamental scientific works on the mechanics of pneumatic tires is given. A mathematical model is proposed for a rubber-cord shell, taking into account the tensile properties of the cord threads and the elastic resistance of the rubber matrix without limiting the magnitude of the deformations, which differs from the mathematical model of the moment-free theory of mesh shells used in pneumatic tires mechanics. …”
