This paper presents results of a finite element (FE) study conducted on /tubular members with dents of various geometries, including dents with circular and elliptical cross-sectional shapes. The modeling and analysis procedures are discussed, and stress concentration factors (SCFs) are generated for axial and bending loads in the member. Equations that give SCFs as function of the member size and dent geometry are developed for both load conditions. Then, simplified equations are proposed for structural assessment purposes.
