Abstract (EN): Forming limit curve is usually utilized to predict failure by necking in conventional sheet metal forming. However in specific cases, like single point incremental forming, it was observed that fracture precedes necking. This lies outside the scope of conventional forming limit curve (FLC) and thus rises the need for the determination of the fracture forming limits. This study verifies the application of the methodology to characterize the plastic flow and fracture forming limits in sheet metal developed by Silva et al. (2008) and Isik et al. (2014) on Copper and Brass. The experimental work consisted in the realization of tensile Nakajima bulge and shear tests, in order to obtain the necking and fracture limits for the materials in study.
