The physical processes accompanying electrical explosion of conductors are varied in nature; solid-liquid metal and liquid-vapor phase transitions, stratum formation, vapor breakdown, arc discharge ignition, etc. [1–6]. At the present time there exists no complete description of this process, even of a qualitative nature. In such a situation it is natural to turn to computer simulation of physical models of the various stages of breakdown, with subsequent verification of results in goal-directed experiments. The present study is dedicated to the initial stage of the breakdown process — the fusion stage. Not much attention has been directed to this stage in experimental and numerical studies of an applied nature, which is natural to a certain degree, since fusion is energetically a less significant process than, e.g., boiling. However, for the justification of theoretical positions (in particular, we will consider a two phase solid metal-liquid model), study of the fusion stage is of significant interest. |
