Dynamic mechanical analysis (abbreviated DMA) is a technique used to study and characterize materials. It is most useful for studying the viscoelastic behavior of polymers. A sinusoidal stress is applied and the strain in the material is measured, allowing one to determine the complex modulus. The temperature of the sample or the frequency of the stress are often varied, leading to variations in the complex modulus; this approach can be used to locate the glass transition temp… WebDynamic mechanical analysis (DMA) measures the mechanical properties of polymeric materials as a function of temperature, time, frequency, stress, or a combination of these … Tensile Testing - Polymer Tensile Properties; Thermogravimetric Analysis … Our plastic and rubber testing laboratories are uniquely equipped to conduct low … Polymer.
