Abstract
A technique is developed to predict the strain and the stress in a fiber under combined relaxation and creep conditions during long-term loading. Stepwise exponential approximations of the characteristic segments in a relaxation curve are suggested for the initial stage of stress relaxation, and they are generalized by an adaptive exponential approximation containing at most two approximation parameters.
