WebDynamic mechanical analysis (DMA) is widely used to explore the viscoelastic properties of polymers that occur as a response to the application of oscillating forces and make conclusions about mobility of polymer chains and the deterioration of polymers’ thermomechanical properties due to hygrothermal ageing effects [6,7]. WebDynamic mechanical analysis, otherwise known as DMA, is a technique such that a small deformation is applied to a sample in a cyclic manner. This allows the material’s response to stress, temperature, frequency and other parameters to be studied. The term is also used to refer to the analyzer that performs the test.
