Since the loss tangent is just the ratio of the loss modulus over the storage modulus (tan δ = E’’/E’), it follows a similar trajectory to the loss modulus. The empiric quality of the loss tangent is ...

Tangent delta, or the loss factor, is a measure of hysteresis and is the ratio of the loss modulus to the storage modulus. Tangent delta is strongly influenced by the choice of polymer. The addition ...

Hence, setting a precondition to cycle for 35,000 cycles at 10Hz was done before acquiring any dynamic data. At 121°C, the modulus was roughly 50% of the modulus value at room temperature. However, ...
