In every sector, large-scale application of a certain bonding method need precise instruments for failure design and prediction. This study looks at how well a structural adhesive (Araldite® 2015) performs on a T-stiffener with composite adherends comprised of an epoxy matrix reinforced with carbon fibres. The goal of this research is to use the Finite Element Method (FEM) and Cohesive Zone Models (CZM) to numerically investigate the behaviour of various T-stiffeners bonded with a structural epoxy adhesive when subjected to peel loads and various geometries. A parametric research was conducted, which included an elastic stress analysis and maximum load (Pm) prediction using CZM modelling, while taking into account the fluctuation of four geometrical parameters: flat adherend thickness (tP), stiffener thickness (tS), and stiffener thickness (tS) (t0), To acquire the best configuration, adjust the overlap length (LO) and the curved deltoid radius (R). The best joint parameters for T-stiffeners could be identified since all of the investigated factors had a significant influence on both stress distributions and Pm.
