Dynamic mechanical analysis (DMA) is used to measure the mechanical and viscoelastic properties of a material as a function of temperature, time and frequency while it is subjected to an oscillating stress. Depending on the measurement mode and the sample geometry, DMA determines either the shear modulus (G), or the Young’s modulus (E). A DMA instrument can determine the viscoelastic behavior, glass transition, damping behavior, phase transitions, relaxation behavior, gelation, mechanical modulus, and softening of materials.
