The initial-boundary value problem of one-dimensional dynamical plastic deformation within the scope of large strain of a metallic cylindrical rod has been analytically solved in a closed form in this paper. The deformation of a flat-ended rod has been caused by its normal impact on a rigid target. The rod material in the deformed part is defined by an incompressible, rigid-plastic, power strain hardening model. Such a model of the material provided better correlation with experimental data than a perfectly-plastic model. Results presented in this paper have applicable values. Derived in the paper closed analytical relations, written by elementary functions, give researchers and engineers insight into interaction of the physical parameters of the rod during of the impact process and post-impact.
