academic.csuohio.edulinear viscoelastic material. At any given time, say t1, the strain is proportional to stress, so that the strain due to 3 at o t1 is three times the strain due to o at the same time. Linear viscoelasticity is a reasonable approximation to the time-dependent behaviour of polymers, and metals and ceramics at relatively low temperatures and under

www.tainstruments.comThe linear viscoelastic region of a material is determined in an oscillatory measurement at a constant frequency with increasing stress or strain amplitude. The measured Moduli remain constant as long as the critical strain has not been reached. The end of the linear region is given by a decrease in viscosity or elastic modulus and an increase of
