Therefore, in this thesis, a new set of models about breaking probability and whitecap coverage is set up using this breaking criterion. Under the assumption of linear ocean waves, and in the light of the theoretical framework about the probabilistic distribution of wave characteristics (Sun Fu 1988), several probabilistic distributions of wave characteristics that is necessary for the estimation of breaking probability and whitecap coverage are derived.

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.

经过本文所进行的数值模拟后我们发现：(1)在层状梯度装甲板的抗侵彻过程中层状功能梯度板比铝板的抗侵彻性能好；(2)在层状梯度装甲板的抗侵彻过程中铺层顺序为0%/57%/0%/26%/0%/12%/0%的功能梯度装甲板的抗侵彻性能最好；(3)通过优化组合层状梯度板的铺层顺序以及增强颗粒的含量可以大大改善梯度板的抗侵彻性能；(4)当SiC颗粒体积含量一定时，增强颗粒连续分布的功能梯度板表现出了优越的抗侵彻性能；(5)增强颗粒连续分布的功能梯度板表面SiC颗粒体积含量越高，分布越不均匀，表面的弹性模量就越高，屈服应力就越高；畜此工业大学硕士研究生学位论丈(6)增强颗粒连续分布的功能梯度装甲板比匀质钢板表现出良好的抗侵彻性能；(7)功能梯度装甲板为整个抗侵彻性的优化设计提供了重要的途径。
