Abstract
The test system at high temperature gradient was developed, and thin-walled cylindrical specimen was designed to carry out tension test at different temperatures and different temperature gradient. Practical method combined with finite element analysis to determinate the relation between stress and strain was developed. Distributions of temperature in specimen were obtained from coupled analysis of flow field and solid, and the temperature was transferred to FEM model by interpolation code. Based on the relation between true stress and true strain at different temperatures, the FEM simulation was carried out at temperature gradient. The result shows that the present temperature gradient has little influence on the tension behavior of specimen. And in this cose it is suitable to investigate the tension behavior of specimen with the usual numerical method.
