Hybrid FEM-SECAM Model for Simulation of Material Restructuring under External Heat Flows

摘要

New hybrid approach combining advantages and possibilities of continual and discrete simulation methods is proposed. The principal scheme of the algorithm of calculations and data exchange between FEM-and SECAM-blocks is worked out. The special algorithm of modified SECA-method is created for simulation of process of reconstructing material cluster structure at interface "thermal barrier coating-substrate". It is shown that by means of purposeful creation of coating structure in the form of "chessboard" it is possible to achieve a considerable decrease of intensity of processes of cracking and coating flake off.
