Numerical calculation of storage and loss modulus from stress
Numerical formulae are given for calculation of storage and loss modulus from the known course of the stress relaxation modulus for linear viscoelastic materials. These formulae involve values of the relaxation modulus at times which are equally spaced on a logarithmic time scale. The ratio between succeeding times corresponds to a factor of two.

Logarithm
In mathematics, the logarithm is the inverse function to exponentiation.That means that the logarithm of a number x to the base b is the exponent to which b must be raised to produce x.For example, since 1000 = 10 3, the logarithm base of 1000 is 3, or log 10 (1000) = 3.The logarithm of x to base b is denoted as log b (x), or without parentheses, log b x.

The storage modulus is often times associated with "stiffness" of a material and is related to the Young''s modulus, E. The dynamic loss modulus is often associated with scale by a factor aT, i.e., an additive factor to the log time-scale. The criteria for the application of time-temperature superpositioning have been described in
