Abstract Scope |
One of the more prominent additive manufacturing (AM) technologies being adopted is laser powder bed fusion (L-PBF) for its capacity to accurately create complex geometries such as porous scaffolds because of its high dimensional resolution. For this reason, the adoption of L-PBF components for dynamic loading situations is of increasing interest for defense systems and low-orbit spacecrafts for potentially improved impact resistance, rapid deployment, and light-weighting. Furthermore, as the residual stresses and defects induced by the cyclic heating and cooling of AM technologies become more defined, the leveraging and manipulation of the resultant mechanical properties of L-PBF components has increased. This work aims to demonstrate the efficacy of using as-built 316L components fabricated via L-PBF for dynamic events by coupling high fidelity simulations of the printing process with sequential explicit tensile simulations. The predicted characterizations will be validated by using high-rate tensile tests from Split-Hopkinson pressure bar experimental data. |
