What is a common feature of dimpled joints?

Dimpled joints are designed to enhance a joint's structural integrity by creating a stronger connection between two metal surfaces. The dimpling process works by displacing material, which results in a more tightly fitting joint that can distribute loads more effectively. This increased surface area and better mechanical interlock contribute significantly to the overall strength and stability of the joint.

While options related to weight, installation complexity, and production cost are considerations in aircraft design, they do not directly relate to the primary advantage of dimpled joints. Dimpled joints typically do not necessarily lead to increased weight or higher costs when compared to traditional joints. Additionally, they tend to be straightforward in terms of installation once the process is understood, as the technique of dimpling is a well-established practice in the industry. Therefore, the emphasis on improved structural integrity is what makes this option the most accurate in describing a common feature of dimpled joints.
