Dynamic Mechanical Analysis (DMA) Testing and Measurement Services

What is Dynamic Mechanical Analysis?

Dynamic mechanical analysis (DMA) is a technique used to study mechanical properties of objects, typically viscoelastic properties of polymer materials. Traditionally, this involves understanding the viscous and elastic mechanical properties of a polymeric material under a constant deflection. In this case, DMA is a powerful tool for monitoring the strain of a material when a sinusoidal stress is applied and allows the understanding of complex time dependent moduli.

What Properties can you Obtain with DMA?

Many time-, frequency- and temperature-dependent properties of polymers can be elucidated from DMA experimentation. The storage modulus (E’ or G’) of a material can be measured, along with the Young’s modulus. Shear, bulk and compressive moduli can be determined through different stressing modes. By modulating the temperature with respect to a constant stress, the glass transition temperature can be also elucidated. Crack propagation experimentation can be used to follow defect formation within a polymer material and may shed insight into how tough a material behaves.

Application Space


There is a wide range of applications which DMA measurements may be applicable for, including:

    • Dynatex International

      I had a request for thermal conductivity information on one of my adhesives and contacted Thermal Analysis Labs. The process was very smooth – I experienced none of the issues typical of other contract labs we work with. The results were delivered on time and I have used the data in our sales literature to help my clients have success in their applications.

    • Abbott

      I am very happy with the testing services I received from Thermal Analysis Labs. I’ve found them very responsive, and they were able to get us the data we needed to get quickly so that we could use it to validate our designs. I refer my other colleagues to them, and they’re my go-to group for thermal testing.
