title = "Fragmentation and ejection for Al-sphere hypervelocity impacting on metal mesh bumper",
abstract = "A two-stage light gas gun was used to launch 2017-T4 Al-sphere projectiles impacting on the metal mesh bumper. The distribution characteristic of the secondary debris clouds caused by Al-sphere impacting metal mesh bumper was studied. The effect of diameter of Al-sphere and braiding parameters of metal mesh on the crater distribution on the witness wall were analyzed. Impact velocities of Al-spheres were varied between 2.76km/s and 4.24km/s. The diameter of projectiles used to simulate space debris ranged from 2mm to 6.4mm. The impact angle was 0°. The crater distribution pattern on the witness wall behind metal mesh bumper with different braiding parameters were obtained. The results indicated that a few of approximative symmetry crater clusters as palpus were observed on the witness wall behind mesh bumper. The number and length of crater clusters were different with the different impact position on mesh bumper and braiding parameters of metal mesh. For the same impact condition, When a blank center position was impacted, the more crater clusters as palpus on the witness wall were caused.",
