Staggered MD and MPM for Multiscale Simulation of Impact Responses

Abstract eng:
A particle-based multiscale simulation procedure is being developed to simulate composite structural responses and multiphase (solid, fluid and gas) interactions under extreme loading conditions, in which molecular dynamics (MD) at nano scale is linked to dissipative particle dynamics (DPD) at meso scale via a hierarchical approach while the DPD is combined with the material point method (MPM) at micro scale within a concurrent framework. Since the DPD forcing flinctions are not well-developed for metals, it is proposed that a staggered MD and MPM procedure be designed for concurrent simulation of impact responses between metal specimens. In the conference, preliminary results will be presented to demonstrate the proposed procedure, and filture research tasks will be discussed on the multiscale and multiphase interactions involving failure evolution.
