| Abstract | The damage properties of polymer bonded explosives under dynamic loading were studied by using ultrasonic evaluation and fractal analysis. Explosive samples were damaged by a long-pulse low-velocity gas gun with a gas buffer under different impact velocities. The microstructures of the samples before and after impact were examined by use of polarized light microscopy. The optical micrographs were analyzed using image processing and fractal theory. Ultrasonic examination was carried out using a pulse through-transmission method. Spectra analyses were carried out using fast Fourier transform(FFT). Characteristic ultrasonic parameters including ultrasonic pulse velocities, attenuation coefficients, spectra area and master frequency were obtained. The correlation between the impact damage and ultrasonic parameters were analyzed. The results show that both ultrasonic parameters and fractal dimension can be used to quantitatively assess the impact damage of plastic bonded explosives. |
