| Abstract: | The factors to affect the momentum partition and transition of stress waves passing an interface of two media have been analysed in this paper.In order to adjust the amplitude and width of the stress impulse in targets,the dependence of velocity and impactor thickness,as well as the flatness area of the wave front in targets are discussed.The examples of the planar GPa pressure explosive loading devices and its applications are given. |

| Keywords: | mechanics of explosion stress wave width planar explosive load stress wave amplitude |
