Finite Element Analysis of High Damping Rubber Bearings Using Nonlinear Viscoelastic Constitutive Model

Abstract

The finite element mixed formulation of nonlinear viscoelasticity and material loading test results of high damping rubber material are presented to simulate mechanical properties of high damping rubber bearing. This finite element formulation is enable to deal with Simo-Taylor viscoelastic and damage model and compressibility of rubber material. Parameters of elastic potential function and damage model are obtained from material loading test. Simulations of horizontal properties of high damping rubber bearing are carried out to demonstrate the applicability of the finite element formulation.
