A non-dimensional theoretical approach to model high-velocity impact on thick woven plates. Steel and Composite Structures, 38(6), 717-737.1229-9367https://hdl.handle.net/10016/33896A theoretical energy-based model to capture the mechanical response of thick woven composite laminates, which are used in such applications as maritime or aerospace, to high-velocity impact was developed. The dependences of the impact phenomenon on material and geometrical parameters were analysed making use of the Vaschy-Buckingham Theorem to provide a non-dimensional framework. The model was divided in three different stages splitting the physical interpretation of the perforation process: a first where different dissipative mechanisms such as compression or shear plugging were considered, a second where a transference of linear momentum was assumed and a third where only friction took place. The model was validated against experimental data along with a 3D finite element model. The numerical simulations were used to validate some of the new hypotheses assumed in the theoretical model to provide a more accurate explanation of the phenomena taking place during a high-velocity impact.21eng© 2021 Techno-Press, Ltd.Analytical modellingEnergy-absorptionFRPImpact behaviorNumerical modellingresearch articleIngeniería Mecánicahttps://doi.org/10.12989/scs.2021.38.6.717open access7176737Steel and Composite Structures38AR/0000028344
