Dynamic Mechanical Analyzer (DMA) measures the mechanical properties of a material as a function of time, temperature, and frequency under an oscillatory load. The DMA works by applying an oscillatory force to the sample at a specific frequency and measuring the resulting deformation. The amplitude and phase of the applied force and the resulting deformation are recorded, allowing for the calculation of various mechanical properties.
By varying the frequency, temperature, and applied stress or strain, the DMA can provide information about the material's viscoelastic properties. Viscoelastic properties refer to their ability to exhibit both elastic and viscous responses when subjected to deformation. The instrument can measure properties like storage modulus (elastic response), loss modulus (viscous response), glass transition temperature, and other mechanical properties.

Viscoelastic properties such as:
- Storage modulus: E', G' (purely elastic component).
- Loss modulus: E", G" (purely viscous component).
- Loss tangent: tan δ (E"/E’), and their dependence on temperature/ frequency.
Damping characteristics and viscoelastic behaviour.
Polymer structure and morphology.
Glass transition temperature Tg.
Primary & secondary relaxation behaviour.
Crystallization processes.
Influence of fillers in polymers, etc.
