Stress Analysis of an Annular Sector Semicircular Cross Section Vessel

Abstract

By using finite element software ANSYS, stress analysis was conducted to the annular sector semicircular cross section vessel which was made up of an annular sector plate, two semicircular plates and a semi-cylindrical with thicknesses of 20mm. The analysis results show that the maximum equivalent stress of the annular sector plate appears in the middle of the plate, and the maximum equivalent stress of the semicircular plate and the semi-cylindrical appear in the inner surface of the connections. The equivalent stress distribution trend of the annular sector plate, semicircular plates and the semi-cylindrical was obtained. Through these researches, the distribution trend of equivalent stress provided a reference for the design of the annular sector semicircular cross section vessel.
