Analysis and testing of adhesively bonded lap joints

PDF Version Also Available for Download.

Description

Detailed studies of adhesively bonded tubular lap joints subjected to axial loads can be efficiently performed with two-dimensional (2D) finite element analyses. However, three-dimensional (3D) analyses are required to model the bending of tubes and the axial loading of many other shapes such as airfoils. Unfortunately, these 3D analyses require significantly more time and computer resources than 2D analyses. Thus, it is of interest to determine whether some aspects of 3D behavior can be captured with 2D analyses. A series of finite element analyses will show that the shear stress in the adhesive of a tubular or an elliptic lap ... continued below

Description

Detailed studies of adhesively bonded tubular lap joints subjected to axial loads can be efficiently performed with two-dimensional (2D) finite element analyses. However, three-dimensional (3D) analyses are required to model the bending of tubes and the axial loading of many other shapes such as airfoils. Unfortunately, these 3D analyses require significantly more time and computer resources than 2D analyses. Thus, it is of interest to determine whether some aspects of 3D behavior can be captured with 2D analyses. A series of finite element analyses will show that the shear stress in the adhesive of a tubular or an elliptic lap joint -- due to a bending load -- can be reasonably estimated with a 2D analysis even though the behavior is 3D. After the agreement between 2D and 3D analyses is detailed, preliminary efforts to assess the importance of adhesive geometry at the end of the bond will be discussed. Experimental measurements of the mechanical properties of a structural adhesive used in joint tests will also be presented. Tension, compression, and stress relaxation data for a filled, amine-cured epoxy adhesive will be discussed.
