The Finite Element Simulation and Analysis of Thermal Stress Field of In-service Tubular Electro-thermal Component ZHANG Xiu-mei1,2,a ZHANG Rui-ying1,2,b LI Quan3 1College of Materials Science and Engineering, Inner Mongolia University of Technology, Hohhot, Inner Mongolia, 010051, China 2Key Laboratory of Light Metal Materials, Hohhot, Inner Mongolia, 010051, China 3 Institute of Structural Materials, Central Iron and Steel Research Institute, Beijing, 100081, China azhxmbb@sina.com, bzhang_ruiying@126.com Keywords: Tubular electro-thermal component; temperature field; thermal stress field; finite element model Abstract.
The physical property of two kinds of the heat resistant tubular materials used for establishing the model is listed in Table 1.
Therefore, for the heat-resistant insulation tubular materials mentioned in the article, the crack caused by the thermal stress is more likely to be found on the inner wall of the tube.

Knowing temperatures at the tool-chip interface is extremely important to optimize the machining condition and to improve the machining performance, furthermore to design high performance materials.
Some additives are contained in novel materials to control the tool wear rate and improve the cutting performance.
Therefore, the indexable insert developed can be utilized for optimizing the cutting condition, improving the cutting performance and designing materials with high-machinability.
