Specifying how stress and strain are to be measured, including directions, allows for many types of elastic moduli to be defined. The four primary ones are: 1. (E) describes tensile and compressive , or the tendency of an object to deform along an axis when opposing forces are applied along that axis; it is defined as the ratio of to . It is often referred to simply as the elastic modulus. [pdf]
The degree of crosslinking is directly related to the stiffness of crosslinked PE. Consequently, the degree of crosslinking of PE can be conveniently evaluated using the storage modulus to establish the quantitative relationship between gel content and storage modulus. [pdf]

Young’s modulus, or storage modulus, is a mechanical property that measures the stiffness of a solid material. It defines the relationship between Stress Stress is defined as a level of force applied on a sample with a well-defined cross section. (Stress = force/area)..

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. [pdf]

The instrumentation of a DMA consists of a 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.

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. [pdf]
