| Abstract: | According to the analysis of the mechanical feature of the section structure, the author adopts a harmonious element model about the displacement in the bend line of section, which is applied to calculate the Stress Intensity Factor(SIF)of the section structure with the Finite Element Method. Compared with the analysis solution, the element model introduced in this paper is available. Then, in the case of the various rivet distance and rivet flexibility,the Stress Intensity Factor(SIF)for three cracked types about the structure rivet stiffened by cracked sections is calculated. The result of calculation is drawn in to a curve. Some conclusion are given from the result curve. |
