Abstract
Mathematical models of the failure behaviors of a rubber material and the laminated rubber bearing are studied. At first, the mechanical behaviors of rubber failure are investigated through shear and tension experiments of the material. In these experiments, an image processing is utilized to trace the deformation field of the specimens accurately. Then, based on the experimental results, a failure criterion is proposed and it is verified in comparison with the results of the failure experiment of a laminated rubber bearing. Finally, utilizing the proposed failure criterion, design equation for the failure of laminated rubber bearing is proposed. This equation also shows good agreement with the experimental result of a bearing.
