5.1.3.4 Tongue and Groove Joint
A tongue and groove joint is made with an edge that consists of a groove running the entire length of the joint and a tongue that fits into the groove. This feature of the tongue and groove creates a mechanically strong and aesthetically pleasing joint. The greater the contact surface, the greater the distribution of stresses along the contact surface. This joint is well suited to a number of stresses, as the joint geometry counteracts many of the weaknesses exhibited under peel stress or stresses perpendicular to the bond line.
