Orbital debris in space offers a constant threat to spacecraft, satellites, and the International Space Station (ISS). There is a growing concern as the number of satellites and other space objects keep increasing year-on-year with advancements in space exploration and orbital activities. The threat posed by the small debris or MMODs (micrometeoroid orbital debris) to satellites and spacecraft can be prevented using Whipple shields made of impact-resistant materials. In the current work, a numerical approach has been utilized to simulate hypervelocity impact of spherical projectiles of diameter 4 mm on monolithic and coated whipple shields to determine the extent of damage, and the deformation behaviour. The simulations were conducted at 3.5 km/s and 5.5 km/s. The computational work was carried out using AUTODYN® module of ANSYS® finite element software.
