| Abstract: | A rectangular opening in a heater was analyzed using stress analysis method and finite element software ANSYS. The strength assessment .was also conducted after the stress classification in the dangerous path. The results indicate that, the primary overall membrane stress intensity, the primary local membrane stress intensity, the primary membrane plus the primary bending stress intensity, the primary stress intensity plus the secondary stress intensity are all satisfied with the requirement, which prove that the strength of the rectangular opening is safe. |
