Chapter 32, Problem 33QTP
When manufacturing the fuselage of a commuter airplane, aluminum plates are adhesively bonded together with lap joints. Because the elastic deformation for a single plate differs from the deformation for two plates in a lap joint, the maximum shear stress in the adhesive is twice as high as the average shear stress. The shear strength of the adhesive is 20 MPa, the tensile strength of the aluminum plates is 95 MPa, and their thickness is 4.0 mm. Calculate the overlapping length needed to make the adhesive joint twice as strong as the aluminum plate.

Silica (silicon oxide) space shuttle tile is bonded to silicone adhesive. (Look up the CTE for both materials). Assume that the strain at the interface between the silica and the silicone can be calculated from the difference in the CTE’s. Calculate the strain at the interface and the stress at the interface when the adhesive/silica interface is heated from 298 K to 348 K. The silicone adhesive is brittle. Will the adhesive crack, given the aforementioned data?
