摘要： The substitution of aluminum alloy roof panels for the low carbon steel roof panels most commonly used in motor vehicles is an attractive option for vehicle mass reduction. Often, however, the remainder of the vehicle body structure continues to be fabricated of steel. The combination of the aluminum alloy roof attached to the steel body may create compressive stresses in the aluminum roof when the body is subjected to elevated temperatures such as those required to cure or bake the paint applied to the body. These stresses may lead to unacceptable appearance features in the visible segment of the roof. By modifying the roof stamping to introduce a tabbed flange for attachment to the body and/or modifying the generally-vertical wall joining the flange to the roof interior, the stresses may be minimized and relocated to segments of the roof not normally visible.
