Abstract
Metal sheets are connected in that a hole is introduced into metal sheets of a first stack, and a region of metal sheets of a second stack are deformed in a stack direction. The deformed region can be plastically deformed in such a way that there is interlocking of the deformed region with at least one metal sheet lying below same. In embodiments, the hole has a shape with a reduced width at the center.
