Abstract
One embodiment includes a system of joined structures that includes a first structure having a first aperture in a composite material. The first aperture has a first interior surface and a first minimum radial extent. The system further includes a second structure having a second aperture in a metallic material. The second aperture has a second interior surface and a second minimum radial extent at least approximately the same as the first minimum radial extent. The system still further includes a coupling device having a first shank section extending through the first aperture and a second shank section extending through the second aperture. The portion of the second shank section applies a first radial force to the second interior surface and the first shank section applies at least approximately no radial force to the first interior surface. The composite material proximate to the first aperture is undamaged.
