A generalized Maxwell model has a distribution of relaxation times, E(t), given by E(t) = kt + k and t = 1, 2, and 3 min only. In a stress relaxation experiment, the initial stress of 2.5 x (108) dyn/cm decays to 1.00 x (108) dyn/cm after 1.50min; 1 dyn/cm = 0.1Pa. What is the expected value of stress 3.75min after the initial stress is applied? (since elongation is not specified, you can simplify the calculation by setting = 1 making the total stress and modulus numerically equal) A generalized Maxwell model has a distribution of relaxation times, E(t), given by E(t) = kt + k and t = 1, 2, and 3 min only.
