#### 5.1.1 Assemblies and Joint Stress Distribution

Alternative joining techniques, such as welding or riveting, have specific benefits in certain situations, such as extreme temperatures and harsh chemical environments, where adhesives may not be suitable. However, in nearly all other circumstances, adhesives can provide an exceptionally robust and reliable solution if the assembly is designed correctly. Adhesive assemblies excel with the uniform distribution of stress, and a well-designed assembly will often be stronger than many alternative joining methods such as riveting or bolting.

As shown in Figure 104, the stress distribution of adhesive bond lines is significantly more uniform than bolting or even welding. The even stress distribution exhibited by a correctly designed bond line has several advantages. It will primarily help prevent substrate fatigue and create a stronger, more impact-resistant assembly.
