Abstract

Adhesive joints have gradually replaced several traditional bonding techniques in industrial applications during the past few years. In this chapter, the cohesive laws of three adhesives, Araldite® AV138, Araldite® 2015 and Sikaforce® 7752, were obtained by the application of an inverse adjustment method between the numerical and experimental load-displacement curves (P-\(\delta\)) of Double-Cantilever Beam (DCB) tests for tensile characterization and End-Notched Flexure (ENF) tests for shear characterization. These rules were then confirmed using Abaqus® with experimental data from single-lap joints (SLJ) and double-lap joints (DLJ). The triangle law accurately anticipated the SLJ and DLJ behaviour for the Araldite® AV138 and Araldite® 2015.
