Abstract
A system for attaching material stack-up layers of at least two layers together using mechanical fasteners is disclosed. The material stack-up comprises at least an upper layer and a lower layer. The lower layer has a relatively constant thickness equal to or greater than 4.0 mm or may have alternating thick and thin areas in which the thickness of the thick area is equal to or greater than 4.0 mm. A mechanical fastener attaches the upper layer and the lower layer and is inserted at least partially into the lower layer. The fastener is inserted into the thick area of the embodiment having alternating thick and thin areas. The lower layer may be any of a variety of materials, including magnesium or any other brittle material. The lower layer may also be a casting, such as a magnesium casting. The mechanical fastener may be any of fasteners, screws or bolts.
