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 for probe loading which provides load for the applied force), a drive shaft support and guidance system to act as a guide for the for. 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]

Viscoelastic properties of materialsPolymers composed of long molecular chains have unique viscoelastic properties, which combine. .
The instrumentation of a DMA consists of a such as a , which measures a change in. A form of rheology, DMA, provides the storage (E’) and loss (E”) modulus. Mainly used on thin films, the storage and loss moduli can be measured as the temperature is ramped, resulting in the measurement of both thermal and mechanical effects on the material’s physical properties.
