Multiphase Numerical Modeling of Dendritic Solidification for Jigsaw Puzzle Generation
We explore an opportunity to expand the stylistic variety of handmade and artisanal jigsaw puzzles through the appication of techniques from natural simulation. Typical jigsaw puzzle designs reflect the manufacturing constraints of die-cut, mass-production methods. We generate novel families of puzzle forms by applying a phase field approach to the simulation of dendritic solidification. We ext...
متن کاملDirect Numerical Simulation of Solid Deformation During Dendritic Solidification
Deformation of the semisolid mush during solidification is a common phenomenon in metal casting and can lead to defects such as hot tears, macrosegregation, and porosity. The morphology of the solidifying mush, including the shape of the dendrites and the distribution of grain boundaries, plays a key role in determining its mechanical behavior. In the current study, a polycrystalline phase-fiel...
متن کاملAtomistic and continuum modeling of dendritic solidification
Due to its technological importance, modeling of dendrite growth in pure metals and alloys remains a significant challenge in the field of materials science. In this review recent achievements in the dendrite modeling problem, using two distinct length scale approaches, are summarized. At the nanometer scale, molecular dynamics and Monte Carlo techniques have been developed to extract two impor...
متن کاملPhase-field Simulation of Dendritic Solidification
We consider the solidi cation of a pure material from its undercooled melt, taking into account e ects of surface tension, kinetic undercooling and crystalline anisotropy. The classical mathematical formulation consists of two heat equations coupled with boundary conditions prescribed at the moving solid-liquid interface. Analytic solutions are known only for a few special cases. Since the prob...
متن کاملTransient Effects in Dendritic Solidification
Dendritic solidification is a common mode of solidification. It is also an important model problem in non-equilibrium physics and pattern formation physics. Current theories couple the transfer of latent heat with selection mechanisms at the interface. Measurements of succinonitrile (SCN) dendrites in microgravity show reasonable agreement between heat transfer predictions and experiment. Howev...
