Fig.13 Nominal compressive strength as a function of radius of hole or pore for the Co-based MG[102] (The dashed lines are the predicted strength curves according to the shear banding dominated fracture mechanism, while the green and red shadow curves give the necessary conditions for splitting cracking of samples with hole and pore, respectively. The green and red shadows were plotted due to the uncertain value of the plane strain fracture toughness of the MG. d is the pillar diameter)
