Abstract
Scarf adhesive joints, characterized by an end-to-end connection between tapered adherents at a given scarf angle (α), are applicable in structural applications, e.g., fiber-reinforced structures, owing to their efficiency. This work presents an analysis on the tensile strength of scarf adhesive joints, considering a and the adhesive type as design parameters. A detailed numerical evaluation is presented, based on the eXtended Finite Element Method (XFEM), following the technique validation with experimental data, for adhesives with different characteristics. The XFEM technique was tested with varying damage initiation and propagation criteria. The XFEM technique was positively validated for specific damage initiation and propagation criteria.
