英文摘要： For "NSAF joint funds Projects with defined goals"-5, this application present a new idea to study the Penetration properties of new ceramic composite armor structures according to the requirement of the applicator. It is believed that the failure and destruction characters of materials in ceramic armor caused by fragment are directly related with the energy dissipation in Penetration process. Through the study of these procedures of materials failure from local damage to integral destruction of structure, the Penetration energy dissipations of these procedures are expected to attain based on material and mechanical relevant principles. And then the efficiency of material dissipating Penetration energy could be revealed. Obviously, the dissipating Penetration energy efficiency of new armor can be investigated by the efficiencies of materials that compose ceramic composite armor. Based on the above idea, the main research contents of our application include: testing and description of materials’ failure from local damage to integral destruction of structure caused in the process of penetration, investigation of formation process of these materials’ failure from local damage to integral destruction of structure and its related energy conversion law under different fragment states, establish of the relationship bet
