The quasi-brittle specimen behavior was investigated thanks to a newly developed compactfour-point bending device devoted for in-situ tomographic measurement. We show that shape of thecrack shape can evaluated on the basis of the differential tomography. Similarly, displacement/strainfields and local fracture toughness was analyzed using the digital image correlation tools.
