  • How to consider Payne Effect in abaqus?

    Recently i came across one MSC software seminar, where they explained, the Payne effect consideration for viscoelastic material analysis and its effect on harmonic results. i have attached the image of it,
    Can anyone tell me, how to consider Payne effect in abaqus for vibration analysis?

    Currently i am doing Viscoelastic analysis in Frequency domain with the help of storage and loss modulus test data.

    The Payne effect is referring to the change in dynamic properties with strain amplitude. You can capture the Payne effect in Abaqus using a simple non-linear viscoelastic material model, such as the BB-model. This, however, only works for time-domain analysis. I'm not sure you can do it in frequency domain.
