A form of thermal analysis rooted in the science of rheology, a branch of mechanics that deals with the flow deformation of materials in terms of force (stress, strain) and time. DMA is a technique in which rheological data for a particular material is generated using a rheometer and software. The material is characterized in terms of its modulus, elasticity, viscosity, damping behavior, and glass transition temperature, and the changes of these with strain, strain rate, temperature, and oscillatory frequency.
