Analysis of Atomistic-to-Continuum (AtC) Coupling Methods

Rich Lehoucq, Pavel Bochev, Mike Parks

Multi-Institution Collaboration:

• Sandia is the lead institution;
• Three Universities
  • Estep (CSU),
  • Gunzburger (FSU),
  • Fish (RPI)

Impact:  Complement existing phenomenological approaches with a systematic understanding via multiscale mathematics.

Approach: abstract blending of atomistic and continuum models over an overlapping subdomain.

Accomplishments:

• 2 accepted journal publications;
• 1 proceedings paper;
• 2 reports submitted;
• Invited paper for a multiscale volume underway
