In this aspect adhesive joints o ff er an advantage over other joining methods, like bolting or riveting, since adhesive are significantly lighter than the metals used in bolts or rivets. In this context it is important to properly assess the capabilities of adhesive joints before they are used in vehicles. Meshless methods are one of the possible ways to analyse adhesive joints. Currently the meshless methods works dedicated to adhesive joints only consider their static behaviour. However, their dynamic behaviour is just as important, especially when considering their use in vehicles where adhesive joints can be subjected to impacts and loading conditions that can vary significantly over time. So, the present work aims at performing an impact analysis of an adhesive joint using a meshless method, to assess the capabilities of this tool in this type of analysis. The results show that the two meshless methods used, the Radial Point Interpolation Method (RPIM) and the Natural Neighbours RPIM (NNRPIM) provide similar stress figures to the FEM in this type of loading, and are thus validated. © 2023 The Authors.

1. Introduction 1. Introduction

Adhesive joints present an important alternative to bolted, welded or riveted joints. They are currently used in several di ff erent applications including cars, wind turbines or ships. This makes it important to study and predict their dynamic behaviour through numerical models. Currently their static behaviour has a large body of studies dedicated to it as the review by Ramalho et al. (2020) shows. Under these loading conditions the strength prediction of adhesive joints can be performed with several di ff erent criteria. There are works using simple continuum mechanics criteria Adhesive joints present an important alternative to bolted, welded or riveted joints.
