Dynamic Mechanical Analysis

“Dynamic mechanical analysis (DMA)” often also called “dynamic mechanical thermal analysis (DMTA)” is an analytical method for determining the viscoelastic properties of materials. The sinusoidal load and deformation amplitude, as well as the phase shift between load and path, are measured as functions of time (frequency). Thus, the complex modulus, the storage modulus, the loss modulus, and the loss factor can all be determined. DMA is the most accurate method for identifying the glass transition temperature of polymers.
