摘要：
Numerical simulations of Meteoroids and Orbital Debris (M/OD) hypervelocity impacts on spacecraft protection systems have been performed with the hydrocode AUTODYN-2D, using two different numerical techniques. Results of induced damage on a three-plates shield are compared with the Light Gas Gun (LGG) experiment data, and debris cloud expansion and mass distribution are compared with the pictures obtained by X-ray high performance camera. Differences in results between the two numerical techniques are underlined, and the influence of some parameters is discussed.
