5.1.3.13 Double Lap Joint
A double lap joint is a well-balanced joint consisting of two outer substrates, each bonded to a third central body. The central body is bonded on both sides. This joint is extremely effective when the central body is subjected to bending moments; it resists the stresses on the central body. If the external supports are subject to forces perpendicular to the substrate, there may be an increase in the stresses at the ends of the external bodies where the bond line meets the central body.
