| Abstract;Experimental investigation of the penetration phenomena associated with oblique high-velocity projectile impact of composed of ceramic faced bumper plate and aluminum structural wall were carried out. The results showed that oblique high-velocity impact penetration phenomena were strongly dependent on impact obliquity. When the angle of obliquity is 30.DEG. or less, the center of the penetration projectile fragments traveled along a original projectile path and the center of the penetration ceramics fragments traveled along a near-normal path between the ceramics faced bumper plate and structural wall a distance 5.2cm away. Therefore, the overlapping of the projectile debris and the ceramics debris clouds concentrate and have a strong penetration damage potential for structural wall under this oblique impact condition. The optimal obliquity impact condition which can separate the projectile debris and the ceramic debris clouds and disperse their damage potentials is found to be effective in reducing structural wall damages. This optimal angle was estimated to have value between 45.DEG. and 50.DEG.. (author abst.) |
