Dynamic mechanical analysis (DMA)

CEVAA carries out and supports manufacturers in dynamic mechanical analysis (DMA).

In order to meet the need for characterization of materials, particularly polymers, CEVAA from 6NAPSE group supports manufacturers in dynamic mechanical analysis (DMA).

Our equipment makes it possible to obtain the mechanical properties of the material. The plate, beam or cylinder type samples have reduced dimensions of a few tens of millimeters. CEVAA offers a great versatility of stress modes.

• Moduli: complex, storage, loss, shear
• Stress modes: traction, compression, shear on embedded sample and bending on “free-free” sample

Following the results of the DMA, it is possible to go further in the definition of material properties such as the Poisson’s ratio.

DMA advantages

From the measurement of the intrinsic properties, the moduli, the loss factor and the glass transition temperature, we can:

• Establish relationships between the structure, the morphology of materials and the performance required for the end use.
• Determine the field of use in temperature, frequency and rate of deformation
• Predict the long-term or extended-frequency behavior of materials using WLF or Arrhenius laws.
