Fracture Analysis of a Square

According to actual working conditions, the heat transformation process of a square-hole honeycomb regenerator was analyzed using a thermo-solid coupling method. The distribution of the temperature field was analyzed first and then, based on the Mohr strength theory, the fracture position of the regenerator was analyzed. It was found that the temperature of the regenerator increased in a wave pattern with increased cycle time. The maximum temperature difference in its steady state was about 240. The variation of the temperature gradient on different parts of the regenerator revealed the same trend with cycle times. The temperature gradient of each node reached the highest at the end of the endothermic period and the beginning of the exothermic period. It was theorized that the position on the center hole with a high temperature gradient would be destroyed first. The stress state in the highest stress point was revealed to be bi-directional compression
