Abstract
A three-dimensional finite element modeling for High Damping Rubber bearings is studied. At first, the constitutive law for High damping rubber is formulated to derive the constitutive tensor. Then, a mixed finite element method is formulated, to which slightly compressible materials with rate form or incremental form of constitutive law are applied. Using the constitutive law and the finite element method developed here, a finite element model of High Damping Rubber Bearings is constructed and it has shown a good agreement with experimental results of the bearing. Finally, the torsional or rotational deformation of the bearing is simulated. In addition, simple and theoretical equations on these deformations are proposed for the design of bearings.
