Lap joints joggle

Joggle lap joints. This is the easiest design for aligning loads. This joint can be made by simply bending the adherends. It also provides a surface to which it is easy to apply pressure. ... 

Single and joggle lap joints (Figure 7.2) are more likely to cause delamina-tion than scarf or beveled lap joints. Strap joints may be used to support bending loads. ... 

Figure 2.31 The rebated (joggled) lap joint. When shear loaded, the correct geometric alignment of the adherends inhibits the generation of tensile forces, normal to the plane of the joint, (at X) which may cleave a simple lap joint prematurely (see Figure 2.29b). This type of joint is particularly useful for sheet metal assembly.

Although the joggle lap joint allows shear stresses to be in the same plane as the bonded parts, it does not combine tensile and shear stresses in line with adherends. The double-butt lap joint, the recessed and landed-scarf joint, and the tongue-and-groove butt joint combine both types of stresses in line and, therefore, are recom-mended ...
