Adhesive joints design

Adhesive joint designers will take maximum advantage of this second effect by designing the joint configuration for protection or by specifying a protective coating and/or sealant around the exposed edges of the adhesive. 

In selecting an adhesive system, one must calculate the strength required. If, for example, you wish to design an adhesive-bonded lifting device for a 50 lb (23 kg) machine component, you can use an adhesive with a 100 psi (0.689 MPa) shear strength and make the bond area 0.5 in (3.2 cm ). You must use this type of joint-strength analysis in all adhesive-joint designs [Ref. 4, pp. 171-172]. 

In the railroad industry, structures usually are designed by applying static load assumptions. In reality, however, cyclic loading, creep, temperature, and environmental influences occur which should be considered in adhesive joint design. Generic physical models taking into account all the possible effects are not applicable for a practical design concept.

From the viewpoint of the adhesive technologist, plastics are an anomaly bonded joints can be made in which the plastic fails before the adhesive, but certain plastics are very difficult to bond. Although plastics often present difficulties in adhesive bonding (Table 4.2), all can be joined successfully with the correct choice of adhesive, joint design, and surface preparation [28] ...
