Currently, the fabrication of canoeing boats is based on composite materials, which find advantage in joining by adhesive bonding. The present work numerically studies, by cohesive zone modelling (CZM), an adhesive joint applied in a canoeing boat, namely the hull/deck joint. The numerical workplan includes the currently used joint configuration and adhesive in the analysis, while different joint configurations and adhesives were also tested. Initially, the CZM approach was validated with experimental results taken from the literature. As a result, CZM was positively validated, followed by numerical assessment of the best geometry-adhesive combination, which significantly improved on the current used joint. © 2024 The Authors.

Introduction Adhesive bonding is increasingly present in society and is seen as an alternative to traditional methods. Actually, conventional joining techniques are restricted to materials with a given minimum thickness to avoid damaging the material during joining (e.g., tearing, bending, burning), adhesives are advantageous because they can be applied to 3rd International Workshop on Plasticity, Damage and Fracture of Engineering Materials (IWPDF 2023) Cohesive zone evaluation of different design solutions for adhesive joints in canoeing boats João C.M.
