COUPLING AND PERCOLATION IN IRREGULAR STRUCTURES OF POLYCRYSTALLINE FERROELECTRICS

Algorithms have been obtained to isolate clusters and determine percol ation in irregular heterogeneous structures. These algorithms are quit e useful for the solution of problems concerned with the formation of microstructure of ferroceramics in the process of its manufacturing. T he computer simulation has indicated that the microstructure of ferroc eramic materials cannot be adequately described by the traditional mic rostructural parameters only, and percolational parameters should be i nvoked for this purpose.
