Abstract of the dataset | The "Longitudinal Concrete Analysis" dataset contains ultrahigh-speed image sequences of concrete surface cylinders under compression testing in a split Hopkinson pressure bar (SHPB) setup, captured with a Kirana7M camera at frame rates between 1 million and 2 million frames per second (Mfps). A Bézier fitting filtering method has been applied to the raw images to correct for inherent image lag errors of the Kirana7M, enabling proper material analysis based using one-dimensional wave theory. The primary use of this dataset is to estimate the longitudinal wave propagation velocity during the first stress wave transit, achieved through the development of an image-sequence-based approach for selecting stress-wave-induced motion points. Additionally, the dataset is used for the estimation of various material properties, including global deformation, concrete velocity, strain, and stress. Strain measurements obtained through the well-established strain gauge technique—commonly used in split Hopkinson bar testing for material analysis—are also provided within the dataset, for validation of the ultrahigh-speed image sequence analysis. | |

Project abstract | To improve the impact resistance of existing concrete structures, various mineral-bonded compositions are being developed, tested, and analyzed at high-impact velocities in the research training group GRK 2250, funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation). To assess the performance of these new mineral-based composites, suitable measurement and evaluation methods are essential for analyzing deformation processes during impact. Ultrahigh-speed cameras, capable of capturing millions of images per second, can be used to observe deformation behavior in detail. By applying photogrammetric techniques to these image sequences, the deformation of the concrete surface under analysis can be quantified. These cameras provide high spatio-temporal resolution, enabling detailed deformation analyses, such as crack propagation and wave propagation, which are key to characterizing the impact resistance of the tested concrete materials. | |
