Özet

Boron Carbide[1,2] has been investigated via non-equilibrium molecular dynamics simulations[3] to examine structural changes that occur as a result of  high temperatures that are released under shock compression. Simulations are carried out at 10 K initial temperature in different crystallographic directions. Shock compression  has been modeled by momentum mirror technique. Dimensions of the structure used in the simulation are 30×30×1200 A3 and 30×46×2242 A3. Structural changes caused by high pressure and temperature were observed. It has been observed that the temperature rises above the melting point in the regions where the pressure exceeds the elasticity limit.

Keywords: Boron Carbide, Shock Compression, Molecular Dynamic.
