Answer
The experimental parameters of interest from the stress relaxation is the relaxation modulus while the parameter of interest for viscoelastic creep tests is creep modulus/compliance.
The relaxation modulus is the ratio of stress measured after 10 s and strain, defined in Equation 15.1. The creep modulus is the ratio of stress and strain taken at a specific time defined in Equation 15.2.
