| 제목 | Computer Simulation and Design for Continuous Conductive Structures in Self-Diagnosis Composites |
| 초록 | Materials produced and used in industries, machines, buildings and our daily life are required to have some intelligent function by means of interaction among different properties in a materials. We need optimize microstructures of a material to have well interacted and intergrated functions at its application. The computer simulation is a promising technique to design microstructures suitable for required performances in materials. The studies of materials design using computer simulation can give us not only basic undestanging about the microstructural development but also new design techniques for material technologies. We have successfully developed the computer simulation techniques by Monte Carlo(MC) method for some characteristic microstructures in self-diagnosis materials with multi-phase and integrated functions. This paper is aimed to study the simulation of various microstructures by the MC method useful for microstructure design in self-diagnosis composites. The plural mechanisms of mass transfer were introduced in the MC method of grain growth and sintering processes at micron size grain and particle, grain growth at solid state, solution-reprecipitation through liquid phase, the transfer of pore lattices for shrinkage. The MC method provided the microstructural design for the effects of initial configuration, liquid phase content, energy balance, particle size and second particle inclusion on grain growth and sintering processed. The MC method for sintering and grain growth can be developed to the simulations for the percolation structure of particle with different aspect ratio in a matrix phase. The three dimensional simulations are useful for the design of more detailed structures of percolation and continuity of particles in composites or pore in porous materials. |
