What is Dynamic Mechanical Analysis (DMA)?

Dynamic Mechanical Analysis (DMA) is a technique used to study the viscoelastic properties of materials. It applies an oscillating force or displacement to a sample and measures the resulting response, allowing determination of storage modulus (elastic component), loss modulus (viscous component), and damping properties as a function of temperature, frequency, or time. DMA is commonly used for characterizing polymers, composites, adhesives, and other materials to understand their behavior under dynamic loading conditions and to determine their glass transition temperature, damping characteristics, and other material properties.
