In this DMA tutorial, we provide information on how Dynamic Mechanical Analysis (DMA) can be applied to help solve your analytical problem.
DMA is an important technique used to measure the dynamic mechanical and viscoelastic properties of materials. The force and displacement amplitudes and phase shift are analyzed as a function of temperature, time and frequency.
In DMA, the sample is subjected to a periodic stress in one of several different modes of deformation. Processes and events measured by the DMA include secondary relaxations, glass transitions, crystallization, solid-solid transitions, crosslinking reactions, melting, flow behavior and the rubbery plateau.
Application examples presented cover the rheological behavior of PET in shear mode, determination of all phase transitions in PTFE measured in shear and tension and the analysis of silicone oil in liquid shear mode. In addition, the characterization of a thin coating, modulus determination of printed circuit board in 3-point bending and the investigation of EVA curing are also presented.
The DMA utilizes revolutionary technology and offers previously unattained performance and timesaving external sample loading.
