Introduction:
DMA is an important technique used to measure the mechanical and viscoelastic properties of materials. The sample is subjected to an oscillating force in one of several different modes of deformation and the force, displacement amplitudes, phase shift are then analyzed as a function of temperature, time and frequency. DMA are used to study various material properties such as viscoelasticity, creep and stress relaxation, glass transition, phase transitions, Young modulus, shear modulus, complex modulus (storage & loss modulus), damping behavior etc.
