Dynamic Mechanical Analysis measures the mechanical properties of materials as a function of time, temperature, and frequency. In addition to quantifying viscoelastic properties of materials, DMA can also quantify finished component and product characteristics, reflecting the important contribution that processing has on end-use product performance. DMA is commonly used to measure glass transition temperatures (Tg) and secondary transitions, orientation caused by processing, cold crystallization, cure optimization, filler effects in composites, and much more. DMA provides an accurate measure of material modulus and product stiffness plus other important mechanical properties such as damping, creep, and stress relaxation.
