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.
