Let's say I have a maxwell body, with a behavior of exponential decay in stress relaxation test. Let's say that that a graph obtained from multiple tests of high molecular polyethleyne.(adsbygoogle = window.adsbygoogle || []).push({});

my question is if I took this graph and drew a tangent line (derivative) about a point what will this represent?

I thought about it, and I think its either the modulus or the dashpot viscosity. based on the formula derivation

stress = Ke^((-E/n)t)

where

ds/dt = -E(1/n)*s s = stress

if its not a modulus, then how would I obtain the modulus?
