4.8 STORAGE AND LOSS MODULUS

Storage modulus and energy loss modulus
The storage modulus relates to the material’s ability to store energy elastically. Similarly, the loss modulus (G” or E”) of a material is the ratio of the viscous (out of phase) component to the stress, and is related to the material’s ability to dissipate stress through heat.

Storage modulus and loss modulus
is studied using where an oscillatory force (stress) is applied to a material and the resulting displacement (strain) is measured. • In purely materials the stress and strain occur in , so that the response of one occurs simultaneously with the other.• In purely materials, there is a between stress and strain, where strain lags stress by a 90 degree ( ) phase lag.

Storage modulus testing mechanism
This approach is called dynamic mechanical analysis. We can use dynamic mechanical analysis to measure the modulus of the material. Instead of continuously moving all the way through the linear elastic region, beyond which Hooke's law breaks down, we carefully keep the sample in the Hookean region for the entire experiment.

Storage modulus relationship
Young’s modulus, or storage modulus, is a mechanical property that measures the stiffness of a solid material. It defines the relationship between stress and Strain Strain describes a deformation of a material, which is loaded mechanically by an external force or stress.

Storage modulus tg
The storage modulus represents the amount of energy stored in the elastic structure of the sample. It is also referred to as the elastic modulus and denoted as E’ (when measured in tension, compression or bending) and G’ (when measured in shear). [pdf][FAQS about Storage modulus tg]

How to measure the fluid storage modulus
This can be done by splitting G* (the "complex" modulus) into two components, plus a useful third value:G'=G*cos (δ) - this is the "storage" or "elastic" modulusG''=G*sin (δ) - this is the "loss" or "plastic" modulustanδ=G''/G' - a measure of how elastic (tanδ<1) or plastic (tanδ>1) [pdf][FAQS about How to measure the fluid storage modulus]

Storage modulus of polymer
The storage modulus determines the solid-like character of a polymer. When the storage modulus is high, the more difficult it is to break down the polymer, which makes it more difficult to force through a nozzle extruder. Therefore, the nozzle can become clogged and the polymer cannot pass through the opening. [pdf][FAQS about Storage modulus of polymer]

Storage modulus measured by rheometer
The values measured by the rheometer (deflection angle, torque, and phase shift) together with the conversion factors for the measuring system now give all necessary data to calculate the required rheological parameters such as the storage modulus G’ or loss modulus G’’.

Influence on rheological storage modulus
On increasing the particle modulus, in suspensions with phase volumes above maximum packing, the storage modulus increases by two orders of magnitude although the loss tangent (tan δ) also increases due to increasing viscous dissipation. [pdf][FAQS about Influence on rheological storage modulus]

Storage modulus measurement instrument
The instrumentation of a DMA consists of a displacement sensor such as a , which measures a change in voltage as a result of the instrument probe moving through a magnetic core, a temperature control system or furnace, a drive motor (a linear motor for probe loading which provides load for the applied force), a drive shaft support and guidance syste.
