| Abstract: |
| A numerical method based on molecular dynamics simulations for modeling thermo-mechanical behaviors of polycrystalline materials at micro-scale is presented.The main point is,the conservation laws should be satisfied both at the continuum models and atomic levels at the micro-scale.Compared with conventional continuum mechanics,the continuum fluxes in our model are calculated through molecular dynamics simulations.Hence,empirical constitutive laws can be bypassed. |
