In this application video, a 2-cam (12 Mpx) MSpeedDIC system was used to measure the strain concentration of cracks
developing in a compression test of an (additive) printed concrete block.
In the correlation evaluation, the startpoint search (used for the 1st iteration of correlation) was performed with multiple
startpoints since cracking within the concrete block formed in multiple locations. The development of the lagrangian
effective (von Mises) strain along the lines of cracking can be seen in the 2D-visualization.
