Five crack types initiated from the preexisting flaws identified in dynamic tests. (a) Type I: coplanar shear crack. (b) Type II: oblique shear crack. (c) Type III: tensile wing crack. (d) Type IV: tensile crack. (e) Type V: mixed shear-tensile crack. (f) Schematic diagram of experimental sample size.
