“…However, in recent years [1][2][3][4][5][6], the interest in crashworthiness studies focus more on the development of numerical modeling resulting from the availability of better computational resources and new explicit finite element codes in order to replace the high cost experimental works. The numerical modeling of composite crashworthiness was initiated in 1989 [7].…”

“…The numerical modeling of composite crashworthiness was initiated in 1989 [7]. Starting from that point, many efforts have been made by many researchers to improve the numerical modeling of composite crashworthiness in various aspects such as the choice of constitutive models [3,4], delamination techniques [4] and triggering mechanisms [5] in order to predict with accuracy the crushing morphology, specific energy absorption (SEA) and force-displacement curve, as observed experimentally. However, the complex nature of fracture behaviors in crushing makes them difficult to be predicted numerically.…”

“…Hence, limitations in numerical models can also result from the choice of modeling scales to predict the crushing mechanisms. Some of the models developed in the past [2][3][4][5]9,10] are based on global test characterizations (macro-scale) making the model strongly dependent on the laminate behavior. Even though this methodology makes modeling simpler and decreases computational time, but it cannot represent the damage mechanisms that takes place at sub-ply scale.…”

This paper describes the development of a numerical model of (0°/90°) CFRP plates subjected to low velocity crushing, based on physical observations. The developed model is represented at the meso-scale and is based on five main ideas: 1 -meshing of each ply of the laminate; 2 -use of cohesive elements to represent delamination and plies splaying; 3 -simulation of macro-scale fragments; 4 -representation of the localized crushing of plies at their extremities with the introduction of a free-face-crushing concept; 5 -representation of contacts between plies, plies and impacted base, plies and debris. The results of the Abaqus/Explicit simulations show a good agreement with the experimental results, which demonstrates that the proposed methodology is able to predict the force, the main failure mechanisms and the phenomenology observed during experiments. Furthermore, an analysis of the repartition of absorbed energies is done, which shows that the most efficient mechanism is the localized crushing in the 0°plies.

“…According to their results, the spot weld-based method can predict the initiation and propagation of delamination with more accuracy. For cohesive models, a different cohesive model can be used, which may lead to the different performances of numerical models [34]. Elmarakbi et al developed a new adoptive cohesive element to overcome numerical instability while using the bilinear cohesive model.…”

Composite pressure vessels can be exposed to extreme loadings, for instance, impact loading, during manufacturing, maintenance, or their service lifetime. These kinds of loadings may provoke both visible and invisible levels of damage, e.g., fiber breakage matrix cracks and delamination and eventually may lead to catastrophic failures. Thus, the quantification and evaluation of such damages are of great importance. Considering the cost of relevant full-scale experiments, a numerical model can be a powerful tool for such a kind of study. This paper aims to provide a numerical study to investigate the capability of different modeling methods to predict delamination in composite vessels. In this study, various numerical modeling aspects, such as element types (solid and shell elements) and material parameters (such as interface properties), were considered to investigate delamination in a composite pressure vessel under low-velocity impact loading. Specifically, solid elements were used to model each layer of the composite pressure vessel, while, in another model, shell elements with composite layup were considered. Compared with the available experimental data from low-velocity impact tests described in the literature, the capability of these two models to predict both mechanical responses and failure phenomena is shown.
