Abstract:
An analytical model is developed to study the coupling effects in cord-rubber composite materials. The analytical model takes into account the mismatch of stiffness between the cords and the rubber matrix material, and the twist-extension coupling. The transverse deformation, i.e., normal to the cords direction is based on the normal modes of a special system which describes the orthotropic and the coupling behaviour of cord-rubber composites. The equations of motion for the cord-composite plates are derived using the principle of virtual work. Results of deformation and stresses are obtained for some typical cord-rubber composite plates and are compared to the existing solutions. The results presented illustrate that the coupling effects are significant for non-symmetrical cord orientations. |
