Abstract
Porous materials are a new category of materials which have attracted the attention of scientists and different industries due to their special mechanical properties (MP), such as definable strength and density. This research aims to study the effects of an electric field on the MP of a silicon nanoparticle (NP)-doped carbon matrix with 10% porosity. MP studied in this research include Young s modulus (YM), and ultimate strength (US), obtained using the molecular dynamics (MD) simulation method and LAMMPS comprehensive software. The results show that the US and YM of silicon-doped nanoporous carbon matrix converged to 69.4014 GPa and 200.192GPa, respectively. In the following, the mechanical strength in simulated samples decreases by increasing the electric field magnitude. Numerically, by increasing the electric field from 0.2 to 0.5 V/Å, the US and YM of silicon-doped nanoporous carbon matrix decreased from 65.83 and 191.022 GPa to 57.81, and 167.18 GPa.
