THE STUDY OF SIZE EFFECTS ON MECHANICAL PROPERTIES AND DEFECTS EVOLUTION IN NANO ALUMINUM BASED ON MOLECULAR DYNAMICS SIMULATION

The size effects on the mechanical properties and defect evolution process of single crystal aluminum with a center crack under tensile loading have been simulated through molecular dynamic method. With the increase of model size, the yield stress and yield point decreased, while the fracture toughn...
