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

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.
