“…Other numerical models such as combined finite-discrete element method (FDEM), which couples the advantage of discrete element method (DEM) in modelling fracturing, fragmentation and that of FEM in modelling polymer behaviour, have also been used in the related topic [7,8]. It shows that in the numerical attempts, in order to improve the computation accuracy, complex mechanical models were kept being developed and implemented into the numerical model [26,27].…”

“…The tensile and compressive behaviour of composite with holes has been studied in numerous contexts including experimental [9][10][11], numerical [12][13][14][15] and analytical [10,16] studies; however, the behaviour of composite structures with open holes subjected to low velocity impact has drawn less attention, despite the severity of the damage that is promoted by low velocity impact. Regarding the influence of the open holes on the damage in initiation composite laminates with open holes, Green et al [17] performed an experimental and numerical study on notched laminates subjected to impact, considering the effect of the diameter of the hole, the thickness of the laminate, and ply.…”

The presence of open holes changes the behaviour of composite laminates when subjected to mechanical loads creating critical zones with a high probability of interlaminar and intralaminar damage initiation. While open holes in composite laminates are a requirement in many situations such as assembly needs, wiring, and maintenance access, their influence on the impact response of composite laminates is still poorly understood. In this paper, a numerical study was performed on Carbon Fibre Reinforced Polymer (CFRP) composite laminates with open holes subjected to low velocity impacts. The influence of the distance between open holes to impact origin, hole diameter, and the number of open holes on mechanical response and failure was studied using a FE model based on the inter-fibre failure criterion of Cuntze to account for the progressive intralaminar failure. The interlaminar failure was considered by using zero thickness cohesive elements based on the cohesive zone model. The results showed that i) open holes change the shape and size of the damage caused by low velocity impact and ii) that the presence of an open hole close to the impact origin in-plane spread of damage is stopped resulting in more severe damage and a smaller projected damage area compared to the control specimen. In addition, the presence of open holes in most cases did not change the locality of the low velocity impact but rather changed the severity of the damage in the local impact zone.
