On Stress Concentration Character at the Abnormal Cross-Section of the Concentric Shaft with Bigger Diameter Ratio
Aiming at the concentric shaft of the abnormal cross-section where there are two types of the concave fillet and the convex fillet and whose diameter ratio is bigger than 2, a 3D finite element computing model was constructed, and the stress and the strain is computed by means of software ANSYS8.0, and a stress concentration coefficient graph is found through comparing the result computed by FEM and by the method of material mechanics. It is concluded that the most important factors effecting the stress concentration are the type and radius of the transition fillet.
