Features of using the viscoelastic material model in the ANSYS software package

Abstract

The paper presents an experiment on uniaxial cyclic stretching with increasing amplitude of a filled elastomeric material. Such materials have complex mechanisms of mechanical behavior, in addition to elasticity, there are viscoelasticity and the Mullins softening effect. According to the experimental data, a mathematical model of a viscoelastic material with a softening effect is constructed in the ANSYS software package. It is shown that the combined use of the Ogden hyperelastic model, the Ogden–Roxburgh softening model, and the Prony viscoelastic model in the ANSYS software package accurately describes the mechanical behavior of the material for a multiplicity of elongation 2.
