Description

The failure mechanisms of an adhesive layer are generally separated into adhesive failure and cohesive failure. A failure is considered to be adhesive when it takes place in a thin boundary layer at the interface of the adhesive and the adherend, and cohesive when it is in the interior of the adhesive layer. To analyze failure of an adhesive bond, the adhesive layer may, therefore, be divided into three layers, namely, two boundary layers and an interior layer. For a typical adhesive bond of the thickness, say, 100 μm, the boundary layers may be of the order of 5–10 μm each.
