dc.description.abstract This work shows a combined experimental-numerical research in bird impact. In order to perform theexperimental tests, a articial bird has been prepared and impacted against a Hopkinson tube in a widerange of impact velocities (70-200 m/s). The Hopkinson tube was designed in order to measure the inducedforce transmitted in the tube by the impact. This force could be used to compare di erent experimentaltests and also to validate the numerical models proposed. In addition, the whole process of impact wasrecorded by means of high speed video cameras. The images captured allow to perform the analysis of thebird kinematics during the impact. Numerically, in order to reproduce the high deformations experiencedby the articial bird in the impact process, the Smooth Particle Hydrodynamics (SPH) technique has beenused. Concerning the articial bird material behaviour, four di erent models were employed, combiningthe two material models and two equations of state most used in the literature. The four cases have beencompared with the experimental measurements and benchmarked. After the analysis of the results, it canbe concluded that the combined experimental-numerical methodology proposed successfully can be used tostudy and validate the numerical models for simulating the behaviour of soft impactor when subjected tohigh velocity impacts. It can be seen that the normal impact forces induced by the impact are reproducedadequately for all the numerical models. However the radial spreading of the soft impactor is not reproducedas adequately as the other cases, especially in low velocity impacts. This e ect can be important to reproducethe radial distribution of pressures and the secondary impacts produced by this radial expansion.
