WebSep 15, 2024 · Dynamic mechanical analysis (DMA) is the technique of applying a stress or strain to a sample at controlled frequencies and analyzing the response to obtain phase angle and deformation data. This data allows the calculation of the damping or tan delta (δ) as well as complex modulus and viscosity data. Two approaches are used: (i) forced ... WebThermomechanical Analysis (TMA): Measures the change of length of a sample. Sensor output is in micrometers (µm). Dynamic Mechanical Analysis (DMA): Measures the modulus (storage/loss) of a material (unit Pascal (Pa)) as a function of time, temperature, or frequency. An additional output is the unitless calculated damping factor tangent delta.
