  17. 17. DMA • Dynamic Mechanical Analysis (DMA) technique used to study and characterize materials. • 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.
