WebJan 26, 2024 · The other dynamic rheological property is loss tangent (tan δ), the ratio of G″/G′, which describes the viscoelastic behavior. Tan δ is directly related to the energy lost per cycle divided by the energy stored per cycle. The values of tan δ <1 and tan δ >1 indicate predominantly elastic and viscous behaviors, respectively.
