Are viscoelastic moduli accurate in rubber friction models?

Up-to-date predictive rubber friction models require viscoelastic modulus information; thus, the accurate representation of storage and loss modulus components is fundamental. This study presents two separate empirical formulations for the complex moduli of viscoelastic materials such as rubber.

Are complex modulus models based on dynamic testing of viscoelastic materials?

This study presents two separate empirical formulations for the complex moduli of viscoelastic materials such as rubber. The majority of complex modulus models found in the literature are based on tabulated dynamic testing data.

What is a complex modulus model?

The majority of complex modulus models found in the literature are based on tabulated dynamic testing data. A wide range of experimentally obtained rubber moduli are used in this study, such as SBR (styrene-butadiene rubber), reinforced SBR with filler particles and typical passenger car tyre rubber.

What is a dynamic or complex modulus?

With the above definitions, the dynamic or complex modulus will have a real and an imaginary part. The real or storage modulus is defined as the ratio between the real part of the stress and the strain: By definition, the modulus of a material is considered as the overall resistance of the material to an applied deformation.

How can silicone rubber materials be constructed with foam/solid alternating multilayered structures?

In this paper, silicone rubber materials with foam/solid alternating multilayered structures were successfully constructed by combining the two methods of multilayered hot-pressing and supercritical carbon dioxide (SCCO 2) foaming.

Does temperature affect storage modulus?

It can be seen from Fig. 13 a that as temperature increases the storage modulus gradually decreases, this relationship is valid since, VE materials exhibit solid state at low temperatures in contrast, at high temperatures the VE tends to exhibit rubber state.
