Fig.6 Illustration of the cracking mechanisms of shear band under compression[58] (a-d) evolutions of crack initiation, growth and linkage inside the shear band and shear affected zone during plastic shearing, with the cracking dominated by creation and coalescence of excess free volume (e) crack initiation at local non-planar sites of shear band due to the shearing induced tensile stress component (f) crack initiation at the intersection point of the major shear band and secondary shear band
