The results show that:(1) The penetration resistance of functionally graded layered armour made of metal Matrix Composites is better than that of the Aluminum plate;(2) The penetration resistance of the functionally graded layered armour whichlay_up is 0%/57%/0%/26%/0%/12%/0% is the best;(3) The resistance penetration of the the functionally graded layered armour can be greately promoted through optimizing the lay_up and volume fraction of the reinforced particle;(4) The functionally graded armour in which the particles distribute continuous has better behavior of resistance penetration when the volume fraction of the reinforcements are constant;(5) The higher volume fraction of the reinforcements at the surface of FGM and the more non-homogeneous the reinforcements distribution, the higher thesurface Youngs Modulus and the flow stress are;(6) The behavior of penetration resistance of the functionally graded armour in which the particles distribute continuously is better than that of homogeneous steel plate;(7) The functionally graded armour provedes a important approach for the optimization and design of the resistance penetration;(8) The numerical results of simulation of the bird striking the aircraft structureshow that the finite element model of the balance leg is effective;(9) The numerical results show that the structure internal force is relative largewhen the bird strikes the top of the balance leg;(10) The process of the birdstrike is thaf.after the bird penetrting through the front skin of the balance leg and striking the front beam,the bird is broken up in three parts.
