Abstract

In this study we present the results of numerical simulation of orbital debris impact on spacecraft shields. The impact response of the stuffed Whipple shield is computed using forward finite difference method. Fragment simulating projectile hitting the crimp composite fabric at an angle 90° is analyzed. The yarn segments between hinged joints at crossovers are modeled using discrete mass-spring-damper in pin-joint systems consisting of planar square lattices. After a certain time of impact; displacement of the fabric, change in the velocities and the failure in the material is computed and depicted graphically. The effect of crimp and areal density on the ballistic performance of the fabric of the stuffed Whipple shield is examined and discussed.
