Dynamic mechanical analysis (DMA) is mainly used to determine viscoelastic material properties. In the measurement, the sample to be examined is subjected to a sinusoidal mechanical stress as well as to a temperature program. The material also responds sinusoidally in the same period with a deformation or elongation. The amplitudes of the force and the deformation are measured as well as the phase shift between force and deformation. The DMA is particularly suitable for the determination of the glass transition since, in contrast to other thermal analysis methods, it is significantly more sensitive. The DMA provides data on temperature application limits, stiffness and damping, flow and relaxation behavior, structure and structure, aging, curing and vulcanization, and is thus an effective tool in research and development. It is also used for quality control, quality assurance and damage analysis.
