“…In addition, the absorbed energy for each energy level was better captured when matrix cracking and splitting were included in the calculations. In particular, for the 7.35 J impact case, the difference is reduced from almost 14% to less than 5.2% (Shi et al 2014a).…”

“…To simulate the four point bending test, the crack density modelled in 90 plies of laminates showed a good agreement with experimental measurement, in particular, the partial and full matrix cracks and their propagation process have been successfully captured by cohesive zone elements (Shi and Soutis 2015). To improve the predicted accuracy for low velocity impact behaviour of composite laminates , the splitting in bottom 0 ply was accurately simulated by inserting cohesive zone elements within individual ply of the model, which was observed in experiment (Shi et al 2014a;Shi and Soutis 2015), as shown in Fig. 6.…”

“…Moreover, the proposed method by Shi et al (2014a) offered an outstanding benefit to predict composite damage that cracks may close once the load was removed, becoming undetectable by X-ray radiography or any other non-destructive detection technique and hence underestimating the severity and extent of internal damage, as shown in Fig. 7.…”

“…(2.30), the constitutive equations applied were found to be almost consistent for predicting the damage initiation and evolution process. Therefore, Shi et al (2014aShi et al ( , 2014b, Shi and Soutis (2015) proposed to simulate matrix cracking/splitting by inserting cohesive elements within each lamina, at space intervals determined from experimental observations.…”

“…3 it can be seen that there is a difference between experimental measurement and numerical prediction, since splitting was not simulated but observed in the X-ray radiographs. The solution to this issue was proposed by Shi et al (2014aShi et al ( , 2014b, Shi and Soutis (2015) using cohesive zone elements, which will be discussed in the following section.…”

The paper presents recent progress on modelling low velocity impact induced damage in fibre reinforced composite laminates. It is important to understand the mechanisms of barely visible impact damage (BVID) and how it affects structural performance. To reduce labour intensive testing, the development of finite element (FE) techniques for simulating impact damage becomes essential and recent effort by the composites research community is reviewed in this work. The FE predicted damage initiation and propagation can be validated by Non Destructive Techniques (NDT) that gives confidence to the developed numerical damage models. A reliable damage simulation can assist the design process to optimise laminate configurations, reduce weight and improve performance of components and structures used in aircraft construction.

Polymeric composites are used worldwide due to their enhanced applications in various sectors such as automotive, defense, aerospace, marine, and many others. Its lightweight and high‐strength applications make it convenient to use in high‐security fields such as defense and aerospace. Thus, it is essential to characterize composite materials for product development. Numerical simulation of composites has advantages over experimental characterization. The paper presents the mechanical behavior of polymer textile composites, employing geometrical modeling and a numerical simulation approach, under several loading conditions such as tension, compression, flexural, and impact loading. Failure mechanisms are also discussed with different failure modes and damage criterions. This review paper is limited to high‐strength fibers, such as carbon, Kevlar, and Glass fibers in unidirectional and woven formation. Various test specimens used in mechanical characterizations are presented with significant research summaries. Classification charts are also provided for a better understanding of the numerical simulation approach for characterizing the mechanical behavior.

The low‐velocity impact response of carbon fiber composite laminates toughened by nickel‐coated carbon fiber (NiCF) veil interleaves was investigated experimentally and numerically. The experimental results indicated that the impact resistance of laminates with a layer of NiCF veil of 34 g/m2 inserted in the midplane was improved, especially in terms of increased peak impact force and residual compressive strength (by 16.15%), and reduced damage area (by 30.92%). The enhancement mechanisms were attributed to the breakage, pull‐out, and crack bridging of the NiCF veil, as well as the peeling of nickel coating, which enhanced the carbon fiber/resin interfacial adhesion. A numerical model based on continuum damage mechanics and cohesive zone model was developed and its validity was verified. The simulation results confirmed that NiCF veils reduced energy absorption by enhancing the interlaminar properties of laminates, thereby reducing impact damage. Moreover, laminates with higher areal density and more layers of NiCF veils had higher impact force and smaller damage area, and thus had better impact resistance.
