The objectives of this study is to numerically characterize the debris cloud distribution that results from orbital hypervelocity collision of a satellite with a secondary object of various sizes up to a complete satellite. The post-collision debris cloud should be characterised in terms of fragment number, mass, area, linear momentum, angular momentum, energy distribution, and directionality. The physical principle of a hypervelocity collision must be simulated and analysed in order to understand the transition between the local damage effect and the catastrophic disruption when varying the energy to mass ratio, the distance between the CoM of thetwo involved objects, the relative-velocity and the type and structure of the intersecting components. The main outcomes shall be (1) on a macroscopic systems level, to understand the propagation of shockwaves throughout a spacecraft due to a hypervelocity collision, (2) to understand the global fragmentation and debris cloud generated due to this collision, and (3) to further understand the catastrophic failure criterion and the energy levels involved.
