The structural optimization of Pt-C high temperature fixed-point crucible

In this paper, by using the finite element analysis software-ANSYS and the direct coupling method, the stress of platinum-carbon (Pt-C) high temperature fixed-point crucible during phase transition process was analyzed. The stress profile of the crucible was identified through the stress diagram analysis. From analyzing the stress diagram, we recommend a novel optimal hybrid crucible structure. Again we use ANSYS to analyze the stress profile of the improved crucible. A better robustness for the hybrid structure can be obtained from the ANSYS calculation.
