Dynamic Mechanical Analysis - an overview | …

L. De Nardo, S. Farè, in Characterization of Polymeric Biomaterials, 2017 Abstract. Dynamic mechanical analysis (DMA) is a basic tool for the characterization of viscoelastic materials, particularly polymers. Applying an oscillatory force to a material, its response can be measured, calculating the viscosity and the stiffness related to temperature, time, or frequency.
