failure increases if one of the two fiber orientations approaches a perpendicular orientation to the cutting line. In addition, the numerical results indicate an earlier failure for an increasing perpendicular orientation. For an increase in fiber volume fraction a higher blanking force as well as an earlier failure of the laminate with respect to the blanking path is expected. Furthermore, the numerical results showed an increase in blanking force due to an increase in blank holder and counter force. An experimental investigation and a validation of the developed numerical model will be performed in the next step.
