Abstract: The finite element method was applied to the thermodynamic analysis of a ceramic stockpot in order to prevent the occurrence of breakage and burst. Pro/E was used to establish the three-dimensional solid model of the ceramic stockpot. Based on ANSYS, the structural analysis of the ceramic stockpot was done via finite element method under the temperature load of 400°C. The distribution of the temperature field and thermal stress was achieved. The results indicated that thermal stress accumulates when the ceramic stockpot is being heated, which leads to the breakage and burst of the stockpot. The analysis of the model showed the accumulating parts of thermal stress are the transitional area between the bottom and the side wall, the neck, and the rim of the open top. A proper structural design can reduce thermal stress accumulation and prevent the occurrence of breakage and burst of the ceramic stockpot.
