Abstract
Microscopic mechanism of plastic deformation of metal is known asslip and motion of dislocation. Althoughmolecular dynamics enables us to simulate such a mechanism of plasticdeformation, the size of numerical model, i.e., the number of atomshas a limitation due to computational resources. In this context, wehere develop a macro-micro simultaneous analysis based on themathematical homogenized method in order to characterize materialproperties through the micro (atomic) scale deformation.
