Abstrakt:
Civil engineering material testing involves various kinds of load and impact experiments on (re-inforced) concrete probes. A major goal in concrete probe material testing is the detection of cracks and deformations. Herein, image-based techniques offer the crucial advantage of delivering precise high-resolved spatio-temporal information on crack positions and crack widths and/or on deformations. In our research, we use ultra-highspeed cameras with up to 7 million frames per second to monitor dynamic deformation processes as well as crack development and crack velocities, which are in the order of 1000 m/s. Beyond image sequences, we also use time-resolved micro-tomography data of probes, necessitating the extension of crack detection and subpixel accuracy crack width determination algorithms from pixel to voxel data.
