| Abstract: | By means of finite-element method, the authors analyze the problem in calculating the stress of a thick-walled square tube with circular inside, and find the rule of its stress distribution. The formula is given that can be used to calculate the stress concentration factors of the danger points on the tube's inside and outside surfaces. |
