In order to establish the mathematical models for predicting the ballistic resistance and set up a relative database for use in future, the fragment simulating projectiles were used to test the specimens with different variations of materials which obeys the U.S. military standard of Vp50 ballistic test for armor “MIL-STD-662F”【1】. The testing specimens include Aermet 100 steel, 1045 steel, 4130 steel of metallic materials and KFRP, GFRP of composite materials. The different material parameters studied in this thesis, such as hardness, thickness, area density of metallic material and pitch content, thickness, area density of composite material, are all the factors influencing the ballistic resistance of armor. Because of the coupling effect by different variations of material parameters, we can use the multiple linear regression analysis method to calculate and set up the single or multiple parameters regression models, known as the ballistic resistance models. Those models can be used to show the relationship and influence on the ballistic resistance of armor, analyze the nearness and predict exactitude of regression by the Multiple Coefficient of Determination “R2”. The analyzed results indicate that the mathematical relationship between the ballistic resistance and the material parameters is a linear equation except the hardness parameter of metallic material. The similar results can be obtained by considering the thickness and area density of material. However, the results will be influenced by materials when taking the multiple thickness-area density parameters. The experimental results of this study are valuable for further research. Moreover, the established mathematical models and database will be very useful for the estimation of ballistic resistance during the design of armor. Chunn-Sheng Mao 毛俊生 1999 學位論文 ; thesis 97 zh-TW |
