Synthetical appraisement applied in fuzzy interface calculation
A fuzzy mathematics method is coupled with Eulerian method to solve threedimension problem of multi-material interface description in Eulerian method. A new method, synthetical appraisement, is firstly presented to dispose multi-material calculation in Eulerian method, which includes description of interface, plan of transport, and computation of transport quantities; three-dimension elastic-plastic hydrodynamic control equations without viscosity and conduction of heat are the basis of calculation, and the stress and strain of solid are considered in the course of material change; a numerical simulation example of exploding in rock are given, and these prove mat the numerical method and interface method are correct and effective.
