| Abstract/Summary |
A concurrent multiscale method has been developed based on the combination of the advanced meshfree method and molecular dynamics (MD). An advanced transition algorithm using regular
transition particles was employed to ensure the compatibility of both displacements and their gradients. An effective local quasi-continuum approach is also applied to obtain the equivalent
continuum strain energy density based on the atomistic potentials and Cauchy-Born rule. The influences of the size of transition region and the number of transition particles are investigated
thoroughly. It has been demonstrated that the present multiscale simulation technique is very accurate and stable, and it has very good potential to develop a practical simulation tool for the
multiscale systems in computational mechanics.
