Resonant Frequency Mode i.e., Time-Oscillation Amplitude

3 Resonant Frequency Mode (i.e., Time-Oscillation Amplitude) 

This mode is used for detection of subtle transitions, which are essential for understanding the molecular behavior of materials and structure-property relationships. Allowing a sample to oscillate at its natural resonance provides higher damping sensitivity than at a fixed frequency, making possible the detection of subtle transitions in the material. Because of its high sensitivity, the resonance mode is particularly useful in analyzing polymer blends and filled polymers, such as reinforced plastics and composites. 

Stress relaxation is defined as a long-term property measured by deforming a sample at a constant displacement (strain) and monitoring decay over a period of time. Stress
