Abstract of the dataset | This dataset comprises the data of the study on Dynamic Spallation Energy Dissipation: Evaluation Methods for Split Hopkinson Bar Tests. In this study, we employ a single high-speed camera setup with photogrammetric methods. The approach is based on enhanced inverse spatial resection principles for 3D tracking from single camera image sequence data and on Structure-from-Motion techniques for 3D shape reconstruction of multiple fragments produced in split Hopkinson bar impact experiments. These fragment shape and motion data allow to estimate the energy of each fragment, providing a key component in the analysis of energy dissipation. | |

Project abstract | Existing concrete or reinforced concrete structures feature, as a rule, a relatively low resistance to various sorts of impact loading, such as shock, collision, or explosion. The primary goal of the Research Training Group is to bring substantial improvements in the impact-resistance of existing buildings by applying thin layers of strengthening material. By using innovative, mineral-bonded composites, public safety and the reliability of vitally important infrastructure should be significantly enhanced. The scientific basis to be developed will additionally enable to build new, impact-resistant structures economically and ecologically. In the analysis of concrete’s energy dissipation in impact events, 3D tracking of fragments and the reconstruction of fragment shapes play a crucial role. Optical 3D measurement techniques offer effective ways to track the motion of objects and to reconstruct their 3D shapes from image sequences captured by high-speed cameras employed in impact experiments. These shape and motion data allow to estimate the energy of each fragment, providing a key component in the analysis of energy dissipation. | |
