| Abstract: | To obtain an approach to a strength equation of a cylinder with complex cracks, the analytical conditions were formed by the orthogonality method and an approximate equation was obtained by regression. Adopting above method, a strength equation for the unwelding portion between a cylinder and its bottom was established with sufficient accuracy in engineering. It simplifies the complicated calculations of the finite element method and is convenient to predict and optimize the strength of a cylinder. The strength equation used for the unwelding portion of a cylinder with arbitrary dimension and load condition provides the basis for analyzing the stress intensity factor. |
