| Summary: | The paper deals with an analytical solution of a one-dimensional boundary value problem, describing behaviour of a ductile porous cylindrical rod, both during and after Taylor direct impact experiment (Taylor DIDIE). The solution provides a simple theoretical basis for dynamical investigations of ductile porous material. The solution was based on a plastic-rigid rate-independent material with strain hardening. For ductile low porous materials with strain hardening, all parameters are presented by means of the closed analytical formulae. The paper presents also a new experimental method of determining distributions of density and longitudinal engineering compressive strain (LECS) in a porous ductile rod, plastically deformed by Taylor DIDIE.[b]Keywords[/b]: Dynamic plasticity, porous ductile material, strain hardening, Taylor impact experiment, deformed rod dynamic parameters
