Abstract
A method of joining substrates includes positioning the substrates on a die and pressing a self-piercing rivet until it penetrates into the bottom substrate and deforms the bottom substrate into a relief of the die defined by at least: a raised central portion, an outer portion disposed about a central axis of the die, a side surface disposed about the central axis, and an annular channel disposed about the central axis and disposed, in a radial direction, between the raised central portion and the outer portion. The side surface connects the outer portion to the top surface. The annular channel is recessed axially from the raised central portion and at least a part of the outer portion that is adjacent to the annular channel. The annular channel is radially inward of a toe of the self-piercing rivet after the deforming the bottom substrate into the relief.
