| Outline of Final Research Achievements |
A combined phase-field/discrete-element method (PFM/DEM) is applied to melted particles, and an elemental process of the powder bed fusion is simulated. In PFM, the migration of interface between particles is computed, and the forces acting between particles are transferred into DEM to compute the motion of particles. The particles in the central circular region of the powder bed are set to be in a liquid state, and fuse together with time, while the solid sintering process is simulated for the surrounding particles.
