Abstract

In this article, potential use of ductile adhesives in structural applications is taken into consideration and their possible advantages over traditional structural adhesives are discussed. For this purpose, the performance of a very ductile adhesive with high strain to failure was investigated in the single lap joint (SLJ) configuration in tensile loading, and the joint was modeled using the finite element method (FEM) to analyze its non-linear solutions. In analyzing the joint, consideration is given to the stress distributions in the adhesive layer and the load to failure was predicted. The predicted values were well in agreement with the previous experimental results, and the stress distributions of the ductile adhesive differed in many respects from traditional structural adhesives. In order to see the differences, a structural modern epoxy has also been analyzed.
