To investigate the effect of microstructure including pores, cracks and inert materials on the shrinkage ratio of coke, a coke model with the microstructure was developed, and a thermal stress analysis using the finite element method was performed. As a result, it was indicated that the pores and cracks did not affect the shrinkage ratio of coke. On the other hand, the inert materials with high stiffness and low contraction coefficient decreased the shrinkage ratio of coke, and the deviator stress appeared at their surface. Assuming the coke matrix was viscoelastic body, the shrinkage ratio of coke increased when the inert materials were arranged. It was suggested that the creep phenomena caused by the deviator stress around the inert materials affected the shrinkage of coke.
