The engineering shear strain is depicted in Fig. 8, which shows the displacement measurements in three phases: the incipient phase and two final stages, before and after fracture. In the second phase, before fracture, the distribution of the engineering shear strain is along the crack and is highly concentrated in that area. The maximum value of the engineering shear strain is 5.5%
