3 DIMENSIONAL FINITE ELEMENT MODEL OF HIGH DAMPING RUBBER BEARING

Abstract

3 dimensional finite element modeling of High Damping Rubber bearing is studied. At first, the constitutive law of High damping rubber materials is formulated for the application to the Finite Element method. Then weak form for updated Lagrangian method of Mixed Finite element method is shown, where slightly compressible materials with incremental form of constitutive law can be applied. Finally FEM model of High Damping Rubber Bearing is constructed and it shows good agreement with experimental results.
