Close examination of the morphology of the dimples on the shear lip shows that they are elongated rather than being equiaxed, and that if dimples are present in the flat region, they can also be elongated or equiaxed. These cases are discussed in more detail following a discussion of the effects...

Visual inspection of the exterior of a joint is used to determine whether a joint contains an adequate amount of adhesive and whether the adhesive appearance and, with probing, the feel rule out a poor state of cure. A continuous bead of adhesive should be visible around the edge of the...
