Dynamic Mechanical Analysis (DMA) is a characterization method that can be used to study the behavior of materials under various conditions, such as temperature, frequency, time, etc. The test methodology of DMA, which aims mainly at the examination of solids, has its roots in rheology (see also "Basics of rheology"), a scientific discipline that studies the viscoelastic properties of

An Introduction to Viscoelasticity Dynamic Mechanical Analysis

Dynamic mechanical analysis is carried out by applying a sinusoidally varying force to a test specimen and measuring the resulting strain response. By analyzing the material response over one cycle, its elastic-spring-like storage modulus and its viscous or flow-like loss (imaginary) modulus can be determined.

Interpreting DMA Curves, Part 1

In Dynamic Mechanical Analysis, DMA, a sample is subjected to a sinusoidal mechanical deformation of frequency, f, and the corresponding forces measured. Conversely, the sample can be subjected to a defined force amplitude and the resulting deformation measured. Storage modulus, M′, proportional to the energy stored elastically and

Introduction to Dynamic Mechanical Analysis and its

If storage modulus is greater than the loss modulus, then the material can be regarded as mainly elastic. Conversely, if loss modulus is greater than storage modulus, then the material is predominantly viscous (it will dissipate more energy than it can store, like a flowing liquid). Since any polymeric material will exhibit both storage and

An example is a temperature sweep DMA test, which monitors modulus as a function of increasing temperature. As a thermoplastic polymer is heated, it will eventually undergo a phase transition where original elasticity is lost and the polymer becomes fluid and deforms irreversibly. DMA storage modulus plots can be used to calculate the Tg

What is Dynamic Mechanical Analysis?

DMA measures the mechanical properties of materials by applying an oscillating force to a sample and measuring its response. The technique allows for the determination of the material''s stiffness and damping properties, which are expressed as the storage modulus (elastic response) and loss modulus (viscous response), respectively.

The slope of the loading curve, analogous to Young''s modulus in a tensile testing experiment, is called the storage modulus, E''. The storage modulus is a measure of how much energy must be put into the sample in order to distort it. The difference between the loading and unloading curves is called the loss modulus, E". It measures energy lost

Dynamic Mechanical Analysis (DMA)

Dynamic mechanical analysis (DMA) is a technique used in material characterization to obtain information about the elastic and viscous properties of a material. Storage modulus is not the same as Young''s modulus (E), which can be obtained from a tensile test. DMA is also a great tool for determining the phase transition temperatures, such

Principle of Dynamic Mechanical Analysis (DMA)

DMA is used for measurement of various types of polymer materials using different deformation modes. There are tension, compression, dual cantilever bending, 3-point bending and shear modes, and the most suitable type should be selected depending on the sample shape, modulus and measurement purpose.
