abstract

In the ASME Code fatigue evaluation, the total stress at the critical region of a structure is often calculated as a product of nominal stress and the SCF (stress concentration factor). The SCF values are usually taken from technical material like the Welding Research Bulletin [1] or Peterson’s Stress Concentration Factors book [2]. However, the published data do not cover all stress concentration cases; furthermore, many results are ambiguous or with limited accuracy. This paper recommends direct evaluation of the stress concentration by finite element analysis. It presents examples of automatic generation of finite element models which apply to practical cases. The examples show that the finite element method is an effective way for stress concentration assessment; the method can give accurate (convergent) results for a wide variety of cases of geometry and loading conditions.
