Dynamic Mechanical Analysis (DMA) (in Shenzhen)

Dynamic mechanical analysis (DMA) (also known as dynamic mechanical spectroscopy) is a technique used to study and characterize materials. It is most useful for studying the viscoelastic behavior of solid materials such as polymers. The analytical instruments report elastic modulus (or storage modulus, G'), viscous modulus (or loss modulus, G'') and damping coefficient (Tand).  They are programmable  for measuring force, stress, strain, frequency and temperature.

DMA instruments apply an oscillating force (stress) and record an oscillating sample response. Moduli are calculated from the elastic response, such as sample response “in phase” with applied oscillatory stress. Damping is calculated from the viscous response when sample response “out of phase” with applied oscillatory stress. DMA is also described as rheology of solids and also Dynamic Mechanical Thermal Analysis (DMTA) when combining the information with temperature response.
