Dynamic Mechanical Analysis (DMA)

Dynamic Mechanical Analysis (DMA) for Mechanical and Electromechanical Characterization of Materials.

Dynamic Mechanical Analysis (DMA) is a technique used to study the mechanical response (stiffness/Young’s modulus, mechanical loss) of a material to an applied oscillatory force. Additionally, our system has been adapted to study the electromechanical response to the applied force. This allows us to measure flexoelectricity and piezoelectricity in addition to the mechanical properties. 

The PerkinElmer DMA 8000 ability to make temperature and frequency scans supplies information about phase transitions and mechanical relaxations.
