FREQUENTLY ASKED QUESTIONSD ynamic Mechanical Analysis (DMA)A beginner s GuideThis booklet provides an introduction to the concepts of Dynamic Mechanical Analysis (DMA). It is written for the materials scientist unfamiliar with Mechanical Analysis (DMA) is a technique that is widely used to characterize a material s properties as a function of temperature, time, frequency, stress, atmosphere or a combination of these parameters. The DMA 8000 dynamic mechanical analyzer is one of the most flexible, cost-effective instruments available today. With a fully rotational sample compartment and accessories you can test samples by simulating real world scenarios easily and of Contents20 Common Questions about DMA 3 What is DMA? 3 How does DMA differ from Thermomechanical Analysis?
modulus when viewed on a log scale against a linear temperature scale, shown in Figure 5. A concurrent peak in the tan delta is also seen. The value reported as the Tg varies with industry with the onset of the E’ drop, the peak of the tan delta, and the peak of the E’ curve being the most commonly used. Figure 4.
