Tensile Deformation Behaviour of Rubber Composite Plate

Deformation behaviour of inhomogeneous composite rubber plate under tensile deformation was studied experimentally and numerically. Two kinds of natural rubber plates were bonded together to make the composite specimen. Strain distribution in the plate was measured from the displacement of the dot marks pasted on the specimen surface. The finite element method for incompressible elastic body was used for the numerical simulation of tensile deformation both under the plane strain and the plane stress conditions. A parameter called constraint ratio was introduced to describe the deformation behaviour of inhomogeneous material, and comparison was made between the experimental and the numerical results.
