Using an elastic-plastic-viscoplastic theory, numerical analysis is carried out for static preloaded materials subjected to dynamic loading. The theory predicts that the slope of the incremental dynamic stress-strain curve coincides with the modulus of longitudinal elasticity at the beginning point of incremental impact, and thereafter, decreases with increasing incremental strain and that incremental dynamic stress corresponding to strain increases with increasing strain rate. Moreover, the theory predicts that speed of the precursor of the incremental impulsive stress wave coincides with that of the longitudinal elastic stress wave at the beginning point of incremental impact, and thereafter, the speed of the incremental impulsive stress wave corresponding to any strain except elastic strain decreases with increasing strain and increases with increasing strain rate.
