Contribution de la fractographie quantitative à l'étude de la rupture dynamique de propergols et d'explosifs composites

Abstract : Tests of Quick traction (20m/s) are achieved to determine the mechanical properties of cristal energetic materials. A fractographic analysis of the aspects and of the sections of rupture is undertaken in order to characterize the mechanisms of rupture. Experimental means such as the Vicom analyser of numerical images, the macrophotographic bench, the scanning electron microscope, the video camera have been used. Thanks to a statistical analysis of measure results of the constraints (tests of dynamical traction) and of microstructural parameters (fractal analysis), we study the influence of those microstructural parameters on the behaviour to the rupture of propergols and compound explosives
