For linear creep, the creep exponent in the steady-state creep rate equation is around 1. S-N curves are a plot of the stress versus the number of cycles to failure. The relaxation modulus is a time-dependent elastic modulus used for viscoelastic polymers. Crystalline polymers show a large drop in the relaxation modulus around the glass transition temperature.
