Annotation	Nonlinear tensile creep occurring in most applications is mainly brought about by the strain-induced increment of the free volume. The superposition of non-linear creep data is proposed to construct a generalized compliance curve. Practical outcome of the format is that the generalized dependence can be employed for predicting the real time-dependent compliance for any stress in the range of reversible strains.
