Figure 27: Equivalent plastic strain field at 0.2 millimeters beneath the impact surface as calculated by means of simulation (continuous line) compared with the plastic strain values calculated form micro-hardness measures by means of the linear correlation taken from Qiao et al. [13]. Abscissa values represent the coordinate along the section of the plate in millimeters.
