| Abstract: | Based on the FEA, the numerical method of thermal-mechanical coupling is presented. With this method, solid grains during its curing process is simulated. The example proves that the numerical method of themal-mechanical coupling can factually simulate the temperature distribute and stress distribute and strain distribute of this structure. A method for the analysis of the grains structural integrality is offered. |
