| Abstract: | In this paper the method to determine the dynamic strain and displacement of the imitative target wearing a bulletproof vest is described. The hit stress data measured from firing practice are analysed in order to establish the distributive functions of stress by using the least-squares approximation. The calcutated results are correspondent with the test data. Then the hit energy subjected by the imitative target can be estimated. How the type and thickness of shimming spacers in bulletproof vest affect on the bulletproof performance is also discussed in this paper. The results and conclusions in this paper are useful for the optimal design of bulletproof vest. |
