The invention relates to a method for simulating the behavior of a bonded joint of two composite material parts (11, 15) with an adhesive material layer (13), comprising the following steps: a) Providing a Finite Element Model with all the relevant information for analyzing said structural joint; b) Providing a calculation model for calculating the deformations of the adhesive material layer (13) when it is subjected to tensile/peel and shear stresses, including a plastic behavior of the adhesive of a linear type under tension/peeling and of a non-linear type under shearing; c) Simulating the behavior of said bonded joint by applying said calculation model to obtain the failure indices of each failure mode. The invention also relates to a system which is useful as an aid in the design of said structural joint using a computer-implemented Finite Element Model of said structural joint.
