Abstract Scope |
When an external force is applied to a solid–liquid coexisting region, characteristic deformation behaviors, which are not observed in perfect solids and liquids, occur. Such deformations, referred to as semi–solid deformations, are characterized by solid–solid interactions, rearrangement of solid grains, and relative motions between liquid and solid grains. Because direct observations of semi-solid deformation are generally quite difficult, numerical simulations are essential to clarify the detail mechanism caused in the semi-solid deformation. In this study, semi–solid deformation was modeled by coupling the phase-field and lattice Boltzmann (PF–LB) methods. High-performance computing for the PF-LB semi-solid deformation was achieved by parallel computing using multiple graphics processing units (GPUs). We simulated some semi-solid deformations using the developed approach. |
