摘要：
An experimental technique is proposed and applied to reveal a possible effect of a geometric surface singularity on ductile fracture during metal forming. The conditions of ductile fracture at the points of geometric singularity are shown not to be predicted by a standard workability diagram. © 2014 Pleiades Publishing, Ltd.
