Effect-of-Graphene-Coating-on-Hypervelocity-Impact-Resistance-of-Aluminium-Molecular-Dynamics
Code is written in LAMMPS and Python.
Hypervelocity is very high velocity, approximately over 3,000 meters per second. This is especially relevant in the field of space exploration and military in anything from minor component degradation to the complete destruction of a spacecraft or missile. Graphene, an allotrope of carbon has a special set of properties which sets it apart from the other allotropes. In relation to its thickness, it is about 100 times stronger than the strongest steel. Yet its density is dramatically lower than any steel. Hypervelocity impact simulations were conducted on Aluminium, one of the most popular and lightweight metals, to study its resistance to these impacts. The resistance to the impacts was measured in terms of the reduction in kinetic energy of the indenter, upon impact with the block. The block was further coated with graphene, and the reduction in energy was monitored.
