This is an abstract for a presentation given at the
11th Foresight Conference on Molecular Nanotechnology

 

Simulation is an effective method to study the mechanical properties of materials. Two kinds of simulations of nano-indentation on copper were carried out: Molecular Dynamics simulation and Finite Element simulation. The molecular dynamic simulation predicted similar mechanical properties of copper as previous works using atomistic simulation. However, such results differ greatly from bulk material properties. When equivalent molecular properties were used in the Finite Element simulation, similar quantitative properties such as force-indentation depth relation can be recovered but other aspects, like deformed shape and stress distribution, continued to show obvious disagreements due to the different theoretical basis of the two kinds of simulations.

Keyword: Nano-indentation, molecular dynamics simulation, Finite element, copper
