Composite Structures, 203, 172-181.0263-8223https://hdl.handle.net/10016/31534In this work, it is proposed a numerical methodology to model the behaviour of composite laminates when they act as impactors at high velocity. The numerical model uses an intralaminar criterion based in the Hashin model and a Progressive Damage model to describe the ply behaviour, whereas the interlaminar failure is taken into account by means of cohesive interactions. The validation of the model is performed attending the kinematics and erosion of the laminate during the impact process onto a rigid target as well as the force and impulse generated. Once validated, the model is used to analyse the influence of the fragment miss-alignment in the impact process.eng© 2018 ElsevierAtribución-NoComercial-SinDerivadas 3.0 EspañaCompositeFragmentHigh-velocity impactNumericalProgressive damage analysisHashin Modelresearch articleIngeniería Mecánica10.1016/j.compstruct.2018.07.002open access172181Composite Structures203AR/0000021999
