Structural analysis of cord-reinforced rubber composites

摘要

The mechanical behavior of cord-reinforced rubber composite structure under tension, bending and torison was investigated using a three-dimensional (3D) beam finite element method. The extension-twisting coupling due to the twisted nature of the cords as well as the coupled extension, bending, and twisting deformations characteristic cord-rubber composite structures wre included in the finite element model. The accurcy of the present approach is demonstrated by comparing the results of coupled stiffness obtained from the finite element analysis to the available experimental data in the literature. The effect of cord orientation on the relative deformation/stiffness under tension, bending and torsion is presented to illustrate the effects of coupled behavior of cord-reinforced rubber composite structures.
