With the material dynamic constitutive equation including damage and the effect of stain rate the predictable formula about ballistic limit velocity of fiber composite target. secondly based on the damage feature about ceramic / fiber composite target caused by impact load, analysis model about defense performance of ceramic / composite material target is formed and the predictable formula about ballistic limit velocity is also given. lastly using the reflection and projectile theory of stress wave the paper discusses the design of ceramic / composite material target, optimizes the design of double layer ceramic / composite targets, gains optimal coefficient under certain area density and discusses the variety relationship of area density and thickness with optimal coefficient u nder some ballistic limit velocity 3
首先，分析了纖維類正交鋪層復合靶板在沖擊載荷作用下的損傷破壞機理，結合包含損傷和應變率效應的材料動態本構方程，建立了纖維復合材料板彈道極限速度的預測公式；其次，根據陶瓷/纖維材料復合靶板在沖擊載荷下的破壞特點，建立了陶瓷/復合材料靶板抗彈性能分析模型，給出了彈道極限速度預測公式；最後，利用應力波反射和透射理論討論了陶瓷/復合材料靶板的設計問題，對雙層陶瓷復合靶板的優化設計進行了分析，給出了在一定面密度下的最佳優化系數，討論了一定彈道極限速度下的面密度和厚度隨優化系數的變化關系。Now, the scholars of internal and overseas pay close attention to the mechanics function of sfrc, such as in the references [ 3, 13, 14, 16, 23, 27, 28, 29 ], and so on. however, in the practice pavement engineering project, the sfrc is given not only the effect of vehicle and shock load, but also the effect of the temperature changes and sun radiation. therefore, the temperature and load stress are the main factor of the damage of the rigid pavement structure. because of the existent of the temperature stress, the sfrc pavement structure may be destroyed by the expand of crack. therefore, the research and analysis of the temperature load and stress of sfrc pavement structure are important to control the crack of sfrc pavement structure
目前，國內外學者對鋼纖維混凝土的研究著重於鋼纖維混凝土的力學性能，如文獻[ 3 ， 13 ， 14 ， 16 ， 23 ， 27 ， 28 ， 29 ]等。而鋼纖維混凝土在實際路面工程的應用中，不僅要受到路面車輛移動載荷和沖擊載荷的作用，還要承受路表的溫度變化及日輻射的作用，所以溫度應力與車輛荷載應力同樣都是剛性路面產生破壞的主要因素。由於溫度應力的存在，會引起鋼纖維混凝土路面板結構產生裂紋。
