“…This work was extended by Jimenez et al [21] for the mixed-mode delamination fatigue analysis. Later studies were also conducted by Cabello et al [22] in the application to a DCB bonded joint in an analytical solution. Both continuum and discrete modeling approaches require a relatively high number of elements to accurately estimate tractions in interface elements.…”

Together with fiber breakage and matrix cracking, delamination is one of the common damage mechanisms occurring in laminated fiber-reinforced composite structures. Delamination initiates due to the relatively low interlaminar strength of adjacent plies. Delamination onset and propagation can be induced by various combinations of loads and usually leads to a significant reduction of the load-carrying capacity of the structure. For this reason, an efficient and reliable progressive failure analysis capability is required. In this work, the de-

“…Cohesive elements, also called decohesion elements or interface elements, are useful in modelling adhesives, bonded interfaces, delamination and rock fracturing [58,65,[231][232][233][234][235]. The constitutive response of these elements depends on the specific application and is based on certain assumptions about the stress and strain states that are appropriate for each application area.…”

“…The damage initiation can be governed by the criteria of maximum stress and maximum strain [60]. Regarding damage evolution law, different cohesive laws have been proposed in the literature, but normally, assumptions of zero adhesive thickness are made (Figure 33) [234,248,249]. Once the damage criteria are met in any one of the modes, then the stiffness starts degrading, causing a gradual failure.…”

The use of composite materials in several sectors, such as aeronautics and automotive, has been gaining distinction in recent years. However, due to their high costs, as well as unique characteristics, consequences of their heterogeneity, they present challenging gaps to be studied. As a result, the finite element method has been used as a way to analyze composite materials subjected to the most distinctive situations. Therefore, this work aims to approach the modeling of composite materials, focusing on material properties, failure criteria, types of elements and main application sectors. From the modeling point of view, different levels of modeling—micro, meso and macro, are presented. Regarding properties, different mechanical characteristics, theories and constitutive relationships involved to model these materials are presented. The text also discusses the types of elements most commonly used to simulate composites, which are solids, peel, plate and cohesive, as well as the various failure criteria developed and used for the simulation of these materials. In addition, the present article lists the main industrial sectors in which composite material simulation is used, and their gains from it, including aeronautics, aerospace, automotive, naval, energy, civil, sports, manufacturing and even electronics.

The adhesive joint is the most widely used joining technique of thermoset composite structures. Analysis of the failure of adhesive joints of composite structures has a high importance due to its significance in industrial applications such as automobile or autobus bodies. In this paper we performed experimental and numerical analysis of a glass fiber reinforced, vinyl-ester matrix composite bonded with a methacrylate adhesive. The critical energy release rate in normal loading direction obtained from standard double cantilever beam test is used as input data in finite element simulations, in which the failure process is modeled by using cohesive zone material. Results of interface elements with exponential and standard contact elements with bilinear cohesive behavior are compared. The use of interface elements is numerically robust, convergence is reached faster, but identical mesh between the parts is needed. It can be a good alternative when simulating sub-models. When using standard contact elements, the robustness needs contact stabilization, however this method does not need identical mesh and it also allows the use of shell elements, therefore it can be used on a full-structure scale with high efficiency.
