Viscoelastic Properties of Rubber Material Modelling

Abstract

Rubber has extensive application in automobiles due to its damping properties and stress relaxation behavior. Its properties largely depends on type of loading (compressive or tensile), temperature, frequency, amplitude etc. The objective of this paper is to show meaningful relation between viscoelastic properties of OGDEN type material solid like rubber under dynamic cyclic loading. Sinusoidal loading is applied to determine stress-strain behavior over time, stress relaxation, and residual stresses. Generally, viscoelastic material gives nonlinear response, but typically it gives minor linear relation initially due to elastic behavior. Material response is visualized at different amplitude of cyclic loading.
