Storage modulus of rubber platform

What is a storage modulus?

The storage modulus is a measure of how much energy must be put into the sample in order to distort it. The difference between the loading and unloading curves is called the loss modulus, E ". It measures energy lost during that cycling strain. Why would energy be lost in this experiment? In a polymer, it has to do chiefly with chain flow.

What is a material modulus?

The Modulus: Measure of materials overall resistance to deformation. Measure of elasticity of material. The ability of the material to store energy. The ability of the material to dissipate energy. Energy lost as heat. Measure of material damping - such as vibration or sound damping.

What is storage modulus in tensile testing?

Some energy was therefore lost. The slope of the loading curve, analogous to Young's modulus in a tensile testing experiment, is called the storage modulus, E '. The storage modulus is a measure of how much energy must be put into the sample in order to distort it.

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.
