“…This formulation leads to the apparition of the parameters defined in Table 1. The dynamic properties at high strain rates, presented in Table 1, used in the theoretical and numerical models are estimated from the static properties obtained in Alonso et al (2018aAlonso et al ( , 2020 taking into account the relations proposed by Harding and Welsh (1983); Harding and Ruiz (1998). The high-strain rate correction factors for the failure limits and for the shear and Young's moduli are estimated at 1.5 and 3, respectively.…”

“…To fully validate the theoretical model presented in the previous section, a 3D numerical model previously developed by the authors has been additionally used (Alonso et al, 2020), where all the properties needed for this model can be found. This model is based on a continuum damage mechanics approach and defines the failure criteria with equivalences to the ones contemplated by the theoretical model (Hashin, 1980;Muñoz et al, 2015;Chang and Chang, 1987;Menna et al, 2011).…”

“…The theoretical model for thin laminates presented in Section 2 accounts for in-plane energy absorption mechanisms such as fibre breakage and matrix failure, and neglects the contribution of shear plugging and crushing. The proposed 3D numerical model, however, includes all the energy absorption mechanisms involved in ballistics to further validate the applicability range of the theoretical model (Alonso et al, 2018a(Alonso et al, , 2020.…”

A new theoretical energy-based model that predicts the ballistic behaviour of thin woven composite laminates is presented. This model formulated for high-velocity impacts, where the boundary conditions (applied at the external edges of the impacted plate) do not play a relevant role. This can be assumed as the mechanical waves do not reach the borders during the impact event, being the local structural behaviour the responsible for the ballistic performance. A non-dimensional formulation is used to analyse the influence of material properties and geometrical parameters in the ballistic response of the laminate. The model is physicallybased on the energy contribution of different energy-absorption mechanisms. A 3D finite element model previously developed is used to simulate the performance of the laminate under high-velocity impacts and to validate the hypotheses of the theoretical model. A comparison between FE and theoretical models is performed by means of energy absorption mechanisms. For that, the failure modes of the FE model are related to the corresponding energy-absorption mechanisms of the theoretical associated. The evaluation of the theoretical results is straightforward although the FEM results require the evaluation of the energy absorbed by each element that fails under each criterion. The predictive capability of the proposed model is verified against experimental results, which were obtained from previous studies carried out by the authors.The results obtained show the dependencies between the ballistic response and the non-dimensional physical parameters of the model. Furthermore, the proposed model can be used to see the relative importance of the different energy-absorption mechanisms involved and the comparison of these mechanisms between the theoretical and the FE models can reflect the different roles played by them, depending on the material properties and geometrical characteristics of the laminate. These results highlight the relevance of the in-plane energy-absorption mechanisms, which rule the penetration process for thin laminates.

In this work, the post‐repair behavior of a quasi‐isotropic laminate was studied in a high‐velocity impact environment. The composite laminates were repaired using an external bonded patch repair procedure. Impact tests were performed to understand the effect of patch size and the result of filling the damaged region with a neat epoxy and hardener mixture. Two different size square patches, such as 30 and 50 mm, were used to analyze the effect of patch size. A continuum damage mechanics‐based model was developed and incorporated into a finite element model interface to estimate the optimum patch size and patch stacking sequence for the impact environment. In the finite element model, the intralaminar failure criteria were implemented using the ABAQUS‐VUMAT user subroutine, and the interlaminar failure criteria were implemented using the inbuilt cohesive contact properties. The 30 mm patch with resin filled in the damaged region performed better than the other combination patches. Also, placing 45° plies toward the outer layer of the patches showed lower damage compared to the patches in which 45° plies were placed at the inner surfaces.Highlights Post‐repair impact behavior of repaired laminates was examined. Impact of patch dimension and resin filling in the damaged area was analyzed. A 3‐D finite element model was developed to optimize patch parameters. Continuum damage mechanics model has been incorporated with VUMAT subroutine. Interface between lamina has been modeled using cohesive contact.

Composite structures in the aerospace and railway industries frequently experience single or multiple low‐ or high‐velocity impacts. The dynamic behavior of composite structures under single impacts cannot be extrapolated to multiple impacts. This study investigates the influence of the distance between projectiles in simultaneous multiple impact scenarios using a finite element model for multiple impacts on carbon fiber‐reinforced polymer (CFRP) laminate plates. The critical distance between projectiles, where stress wave interaction becomes significant, was identified. Results indicate that a distance between the centres of the projectiles of approximately two to three times the projectile diameter is the most damaging for simultaneous multiple impacts.Highlights A finite element model for multiple impacts on CFRP laminate plates was developed. Four different distances between projectiles were evaluated. The ballistic limit, out‐of‐plane displacements, energy absorption, and related parameters were studied. A distance of twice the projectile diameter was identified as the most critical. The distance between projectiles significantly affects the synergistic effects.
