Systems and methods for joining components by riveting

A rivet-formed joint comprising:

• a first workpiece;
• a second workpiece having an interface surface facing the first workpiece and an opposed back surface;
• and
• a rivet comprising a rivet head and a rivet leg, the rivet head being implanted in the first workpiece and the rivet leg extending from the rivet head and through the second workpiece, the rivet leg flaring outwardly and upwardly to form a hook portion of the rivet leg in which a distal tip of the rivet leg penetrates into the back surface of the second workpiece, wherein a gap is formed between the back surface of the second workpiece and the hook portion of the rivet leg.
