Dynamic mechanical analysis (abbreviated DMA) is a technique used to study and characterize materials. It is most useful for studying the viscoelastic behavior of polymers. A sinusoidal stress is applied and the strain in the material is measured, allowing one to determine the complex modulus. The temperature of the sample or the frequency of the stress are often varied, leading to variations in the complex modulus; this approach can be used to locate the glass transition tempe…

As the applied frequency becomes higher, the material becomes more like a solid (higher storage modulus) and at lower frequencies liquid-like (lower storage modulus) behaviour will dominate. Hence the modulus response to the variations in frequencies is an important measure to find the applications of solids in different fields.
