Analysis and testing of adhesively bonded lap joints
- Sandia National Labs., Albuquerque, NM (United States)
Adhesively bonded tubular lap joints subjected to axial loads can be efficiently analyzed with two-dimensional (2D) finite element models. However, three-dimensional (3D) analyses are required to model the bending of tubes and the axial loading of many other shapes. As 3D analyses require more computer resources than 2D analyses, 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. After the agreement between 2D and 3D analyses is detailed, a preliminary assessment of the adhesive geometry at the end of the bond will be discussed. Experimental measurements of the mechanical properties (tension, compression, and stress relaxation) of a structural adhesive will also be presented.
