Description: This paper presents results for a detailed inelastic finite element analysis for a part of the Clinch River Breeder Reactor Control Rod Drive Mechanism. The analysis results indicate that plastic strain concentration factors may in fact be less than corresponding elastic strain concentration factors for nominal strains as low as .2%. This is particularly insightful in that it is presently common practice to approximate inelastic strain concentration factors as the square of the elastic concentration factors. The paper also examines Neuber's relation for predicting strain concentration factors and looks at the variation in the strain concentration factor through the cross-section of the component analyzed.
