¡¾·­Òë¡¿ Fig.4 shows the crack fails to propagate when the strain Ex<10% (Fig.4a), while the crack appear propagatin when the strain Ex>=10% (Fig.4b and c). Thus, for uniaxial tension, the critical stain of crack propagation is 10%.

The fact that the crack does not or does propagate depend upon whether the strain Ex is less than 10%  (Fig.4a) or greater or equal to 10% (Fig.4b and c), indicates that the critical strain value of crack propagation is 10% for uniaxial tension.
