Dynamic Brazilian Test for Mechanical Characterization of Ceramic Ballistic Protection

Figure 7

Analysis of the results obtained from dynamic Brazilian test. In the diagrams: equilibrium check by the comparison between input (gray curve) and output (black curve) forces; COD (red curve with markers) calculated by the vertical displacements measured by virtual strain gages placed along the diameter above and under the crack. The images represent two subsequent frames recorded after fracture: DIC analysis for the evaluation of the vertical displacement.
