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.
A Dynamic Mechanical Analyzer is a mechanical instrument that applies specific displacement or force to a sample and very accurately quantifies its force versus displacement response.
Dynamic mechanical analysis (DMA), also known as forced oscillatory measurements and dynamic rheology, is a basic tool used to measure the viscoelastic properties of materials (particularly polymers).
DMA 8000 Dynamic Mechanical Analyzer. The DMA 8000 is flexible and cost effective. Its innovative design, high functionality, and flexible operation make it ideal for advanced research and routine quality testing in the polymers, composites, pharmaceutical, and food industries.
Dynamic Mechanical Analysis (DMA) Determine the force and displacement amplitudes as well as phase shifts with the dynamic mechanical analyzer. The unparalleled versatility of the DMA 1 allows applications to be performed in the optimum measurement configuration.
A Dynamic Mechanical Analysis, otherwise known as DMA, is a technique where a small deformation is applied to a sample in a cyclic manner. This allows the materials response to stress, temperature, frequency and other values to be studied. The term is also used to refer to the analyzer that performs the test.

Dynamic Mechanical Analyzers (DMA) precisely quantify the viscoelastic properties of your material as a function of temperature, time, frequency and amplitude. DMAs are mainly used to determine the material’s modulus and stiffness, but also its damping properties, creep and relaxation.
A Dynamic Mechanical Analyzer (DMA) measures the mechanical/rheological properties of a material as a function of time, frequency, temperature, stress and strain. Typical materials tested on a DMA. Thermal plastic and thermosets. Elastomers/ rubbers. Gels.
Definitions of Dynamic Mechanical Analysis (DMA) A technique in which the sample's kinetic properties are analyzed by measuring the strain or stress that is generated as a result of strain or stress, varies (oscillate) with time, applied to the sample. Static Viscoelasticity Measurement.
