  • Abstract
    Dynamic mechanical properties of domain structure in BaTiO3 nano-film are investigated using molecular dynamics simulation method based on a shell model. The evolution of the 180 degree domain structure in BaTiO3 nano-films is simulated under different strain rates. Stress-strain curves of the BaTiO3 nano-film under different strain rates are obtained. The strain rate effect is not found in the BaTiO3 nano-film without lattice defect.
