''[[viscoelastic|'''Dynamic mechanical analysis''' (abbreviated '''DMA''') is a technique used to study and characterize materials. It is most useful for studying the [[viscoelastic|viscoelastic]] behavior of [[polymer|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|glass temperaturetransition]] temperature<ref>{{cite web |url=https://coventivecomposites.com/explainers/dynamic-mechanical-analysis-dma/|accessdate=2018-10-01|title=What is Dynamic Mechanical Analysis (DMA)?}}</ref> [[viscoelastic|of the material, as well as to identify transitions corresponding to other molecular motions. That's all about of Temp. In short.]]''
