【Abstract】 In this paper, the competing effect of the impact shear failure and tensile failure on the DFRP(Dyneema fiber reinforced plastic)ballistic target failure is analyzed by the polymer stress-strain model of JRG-cluster statistic theory. A analytical model of DFRP ballistic target failure is established and a empirical eolation of estimating ballistic energy absorption is deduced. The study result has academic significance and practical value for the optimum design of DFRP ballistic target.更多还原
