Dynamic mechanical analysis (DMA) is used to measure the mechanical properties of viscoelastic materials as a function of temperature or frequency. It is one of the most important thermal analysis techniques alongside the well-established DSC, TGA, and TMA techniques.
DMA allows you to determine modulus values and measure relaxation effects that often cannot be detected by DSC.
Dynamic mechanical analysis (DMA) is used to measure the mechanical properties of viscoelastic materials as a function of temperature or frequency when the materials are deformed under the action of a periodic force or displacement. The types of materials that can be analyzed include thermoplastics, thermosets, composites, elastomers, ceramics and metals.
DMA provides quantitative and qualitative information on:
- Young’s modulus and shear modulus values
- Damping characteristics and viscoelastic behavior
- Polymer structure and morphology
- Flow and relaxation behavior
This kind of information is very important for process and application engineers, materials research scientists, and physical chemists.
In this Webinar, we will show the basic principles of DMA and present some interesting application examples.
