Abstract

In this study, the mechanical improvement of the platinum coated nanoporous gold is investigated by performing molecular dynamics simulations. The tensile properties of the structure is enhanced by a stress relief annealing which prevents the high stress concentration observed between the coating and the core materials. The annealing process is performed at 500K for 100ps with a heating and cooling rate of 1K/ps. After the annealing process, tensile loading is applied to the coated structure with a strain rate of 0.001ps-1. According to the result of the tensile analysis, the Young’s modulus increases from 12.2 to 15.25 GPa while the yield strength enhances from 584 to 615 MPa.
