DMA-101 Dynamic Thermomechanical Analyzer

A dynamic mechanical analyzer (DMA) measures the mechanical properties of materials as a function of time, temperature, and frequency. By applying force to the material in a dynamic oscillating environment to induce deformation, it can measure the viscoelasticity of the material and the functional relationship of this viscoelasticity with parameters such as temperature, time, frequency, stress, atmosphere, or a combination of these parameters. It is widely used in fields such as plastics, rubber, films, fibers, coatings, ceramics, glass, metal materials, and composite materials.
