A dynamic mechanical analyzer is a machine that performs vigorous automatic analysis. This process is also known as vigorous automatic spectroscopy. This is a process used to gather information about a sample and arrange the information so obtained in accordance with certain principles.
The basic principle of this machine is to expose a sample with certain measurements to waves with certain known properties . Gauging the effects yields the sample's aptitude to bend or deform under pressure, and its ability to go back to its former shape. This information can then be used to calculate some physical properties of the sample. These include the material's complex-modulus and its ability to lose stored energy.
This enables the researcher to find out different characteristics of material under study when exposed to varying strain levels. To get an even clearer picture, variations in temperature are also introduced. Their effects on the material are then noted.
Apart from temperature and strain, other variables are used in this analysis. These are time, frequency and force. For instance, the material under study is tested on how it behaves under a certain force, which produces a certain amount of strain and stress, over a certain period of time, in a given temperature. These variables can then be varied in order to arrive at a coherent picture of the material under different conditions.
The third test is a combined sweep. This involves a combination of temperature and frequency sweeps. This results in detailed information of the taster, and a clearer image of how the sample behaves under a variety of conditions.
Storage modulus describes the energy stored during deformations that can be lost when the material goes back to its former shape. The loss modulus describes energy lost during transformation. The loss tangent shows the ability of a material to lose energy; its also known as the damping or loss factor. The complex vigorous modulus is another principle underlying the operations of dynamic mechanical analyzer; it describes the ratio of applied stress to the measured strain. These, and other principles, form the basis on which the machines operate.
