Semicircular Cross Section

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.

Annular Sector Plate

In this study, an analytical solution for the buckling of a functionally graded annular sector plate resting on an elastic foundation is presented. The buckling analysis of the functionally graded annular sector plate is investigated for two typical, Winkler and Pasternak, elastic foundations. The equilibrium and stability equations are derived according to the Kirchhoff's plate theory using the energy method. In order to decouple the highly coupled stability equations, two new functions are introduced. The decoupled equations are solved analytically for a plate having simply supported boundary conditions on two radial edges. Satisfying the boundary conditions on the circular edges of the plate yields an eigenvalue problem for finding the critical buckling load. Extensive results pertaining to critical buckling load are presented and the effects of boundary conditions, volume fraction, annularity, plate thickness, and elastic foundation are studied.

The Relationship

Biomass is a renewable energy. Its curing and molding technology is one of the key technologies and mould structure parameter is a important factor. A model is set based on ANSYS to simulate the molding, then the equivalent stress field and frictional force distribution of mould are founded. Finally, the relationship between maximum equivalent stress and mould parameter is studied.
