摘要：
A theoretical model for the description of relaxation curves after dynamic loading is presented in this paper. The model is based on a nonlinear spring placed in parallel with Maxwell elements. The obtained formula is fitted on experimental relaxation curves using the Marquardt-algorithm for nonlinear regression. Relaxation curves can be classified into ordinary relaxation, mixed relaxation and inverse relaxation curves. There seems to be good correspondence between the experimental and the fitted relaxation curves.
