| Research Abstract |
We had investigated an unsteady phase transition phenomenon of an atomic layr which is irradiated by thermal radiation and is being melted, on bases of an electromagnetic theory and a molecular dynamics (MD). This project is on the extention of that work, where is requested a development in a new thermal conduction technique for investigating the dynamics of phase transition and radiation phenomenon, particularly a relationship between the solidification and the radiation emission cooling in a nm-scale atomic system. The real atomic system of a finite size and in a solid state is pressed anisotropically and includes crystal defects. It has a temperature distribution in it. Thermal energy flows inhomogeneously. The MD simulation on such a phenomenon is related to a macrophenomenon on the thermal contact resistance of solid surfaces. First, we prese nted new techniques for a pressure-control-type strain application and for a quasi-static scanning of applied anisotropic pressure, and investigated an unsteady process of elastic and/or plastic deformation in a pressure applied atomic system.Second, we investigated the unsteady behavior of temperature distribution and thermal energy flow in such an atomic system.
