Abstract Scope |
Additive manufacturing of metals is rapidly advancing as a robust method for production of geometrically complex parts. To enhance the understanding of material performance and open additional application opportunities, dynamic characterization of printed alloys is required to validate their effectiveness and identify appropriate models. Here, we present results from plate impact testing of a high-strength steel (AF9628) used in applications requiring resistance to high-rate deformation. We show experimentally differences in the shock structure between the AM and traditionally processed material. We model the impact response with an elastic-plastic damage model accounting for the effects of the tension-compression asymmetry in strength and its influence on porosity evolution. Finite-element simulations show that a very small initial porosity has strong effects on the shock structure. Furthermore, comparison between FE results and experiments for both the AM and wrought material demonstrate the model capabilities to predict the dynamic behavior of AM martensitic steels. |
