DMA Application Notes

dma, elastomer

In materials characterization, what is DMA?

Dynamic Mechanical Analysis (DMA) is a dynamic characterization technique that measures stress as a function of strain, or force as a function of displacement. It involves applying a sinusoidal strain to the material and measuring the resulting stress. 

Why do people conduct DMA tests on materials?

DMA is especially useful for characterizing the properties and behaviors of elastomers, polymers and shape memory alloys. These materials all exhibit damping and are often used in applications where operation at higher frequencies is critical. 

What equipment is needed for dynamic mechanical analysis?

Basic equipment for DMA includes a dynamic test system, high dynamic displacement and force transducers, a robust control system, software that can perform DMA, and an environmental chamber if conducting thermal analysis.
